Description

Wireless communication apparatus

Technical field

The utility model is relevant for a kind of wireless communication apparatus, particularly a kind of orthogonal wireless communication apparatus of polarised direction that makes each antenna.

Background technology

Along with the fast development of wireless network science and technology, much more more and more electronic products are arranged, all (Local Area Network LAN) carries out the transmission of data by LAN gradually as desktop PC or mobile computer.Traditionally, between LAN and the computer equipment by cable as the media that electrically connects, but concerning frequent needs move outside or the user who uses in different public places, with the connecting line of cable as LAN, when mobile or conversion place to use, can't get in touch, for quite inconvenience of user with network.

In view of this, communication industry there's no one who doesn't or isn't is devoted to wireless network (Wireless LAN at present, WLAN) research and development of technology, replace tradition with wireless communication mode and carry out data transmission manner with cable, in wireless communication apparatus, most important spare part is exactly in order to receiving the antenna (Antenna) of wireless signal, and the communication transmission quality of antenna and wireless communication apparatus, communication context, reaches transmission speed utmost point confidential relation is arranged.The antenna major part that wireless communication apparatus is commonly used is flagpole antenna, if antenna is perpendicular on the horizontal plane time, wireless communication apparatus promptly produces the radiation pattern of omni-directional (Omni-Directional) in horizontal direction, but incites somebody to action variation relatively in the radiation pattern of vertical direction, and vice versa.That is to say that for a flagpole antenna, the isotropic radiation pattern that satisfy horizontal direction or vertical direction simultaneously is difficult to accomplish.

Because the wireless communication apparatus of single antenna can only obtain isotropic radiation field at a specific direction, the efficient that causes wireless communication apparatus to receive wireless signal is not cited.Therefore, develop the wireless communication apparatus of the multiple antenna that double antenna or triantennary then, with reinforcement wireless signal receiving intensity, and the communication context of expansion wireless communication apparatus.

Wherein, the putting position of each antenna of wireless communication apparatus must satisfy the restriction at a distance of 1/4 wavelength (λ) of carrier frequency, begin to receive wireless signal, and the Antenna Design of the wireless communication apparatus of commonly using is for rotating the kenel of adjustment arbitrarily, if the user moves because of carelessness the antenna of finishing is set, the change of the polarised direction of antenna will be caused, cause the phase mutual interference and produce the problem of antenna cross talk (AntennaCrosstalk) to each other of each antenna, and then have influence on the transmission usefulness of wireless communication apparatus, thus, the user is adjusted to time that must overspending the position of optimum reception usefulness again with each antenna.

The utility model content

Problem to be solved in the utility model provides a kind of wireless communication apparatus, is easy to generate the phase mutual interference and causes antenna cross talk with the multiple antenna of improveing prior art, and then influence the shortcoming of antenna performance.

For reaching above-mentioned purpose, wireless communication apparatus of the present utility model, form to carry out the function of wireless transmission by a plurality of electronics spare parts, it includes a housing and a plurality of antenna, its middle shell has an accommodation space in order to the holding electronic spare part, and be provided with in the housing peripheral region and a plurality of the orthogonal installing department of direction be set, and a plurality of antenna is arranged at respectively in each installing department, so that the polarised direction of each adjacent antenna is vertical mutually.

Effect of the present utility model is a plurality of antennas are installed in each installing department of housing, so that the polarised direction normality of each adjacent antenna remains in orthogonal angle, it is minimum to cause interference between each antenna to be reduced to, and makes the signal receiving strength of wireless communication apparatus and communication context reach optimization.

140 mobile radios, 200 electronics spare parts

Embodiment

According to the disclosed wireless communication apparatus of the utility model, including, but not limited to network bridge (Access Point, AP), router radio transmitting devices such as (Router), in following detailed description of the present utility model, will be with network bridge (AP) as most preferred embodiment of the present utility model.Yet accompanying drawing only provides reference and explanation, is not in order to restriction the utility model.

Figure 1 shows that the schematic perspective view of the utility model first embodiment.As shown in the figure, the wireless communication apparatus 100 that the utility model discloses, form by a plurality of electronics spare parts 200, in order to carry out the function of wireless transmission, wireless communication apparatus 100 includes a housing 110 and three antennas 130, its middle shell 110 has an accommodation space in order to holding electronic spare part 200, and be provided with three extensions in housing 110 peripheries the orthogonal installing department 120 of direction is set, and three antennas 130 are arranged at respectively in the installing department 120 of housing 110, it is identical to make placing direction and the extension of installing department 120 of antenna 130 that direction is set, cause the polarised direction of each adjacent antenna 130 vertical mutually, to reduce to the signal interference of 130 on each antenna minimum.

As shown in Figure 1, wherein the two adjacent installing departments 120 that disclose of the utility model are miter angle with housing 110 bottoms respectively and are obliquely installed, to be an angle of 90 degrees vertical so that the extension of two adjacent installing departments 120 is provided with direction, cause the polarised direction of adjacent two antennas 130 that are arranged at installing department 120 also vertical mutually, to form the kenel of perpendicular polarization.It should be noted that, two adjacent installing departments 120 only must satisfy the restriction that two angles add up to an angle of 90 degrees with the angle design of housing 110 bottoms, can change being designed to the multiple two angle angles that cooperatively interact, and then housing 110 profiles of the different kenels of deriving, do not exceed with present embodiment.

Fig. 2 A and Fig. 2 B are depicted as the schematic perspective view of the utility model second embodiment.As shown in the figure, wherein more housing 110 1 end-grain cutting can be cut and form a plane, and two antennas 130 are set respectively in the both sides on this plane, and the polarised direction of two antennas 130 is vertical mutually, and the mobile radio 140 that is pivoted in vicinity two antennas 130 places on plane, the user optionally is adjusted to mobile radio 140 activities the vertical position of polarised direction with two adjacent antennas 130, to obtain best reception usefulness, and restraint antenna 140 on housing 110 less than pivoting in an angle of 90 degrees scope, to avoid the user mobile radio 140 is adjusted the position that surpasses perpendicular polarization.

Compared with prior art, the utility model is arranged at a plurality of antennas in each installing department that is vertical angle mutually, so that the polarised direction normality of each adjacent antenna remains in orthogonal angle, and form the perpendicular polarization kenel of signal interference minimum, cause the signal receiving strength and the communication context optimization of wireless communication apparatus.

Though embodiment of the present utility model discloses as mentioned above; so be not in order to limit the utility model; anyly have the knack of related art techniques person; in not breaking away from spirit and scope of the present utility model; such as work as according to the described shape of the utility model right, structure, feature and spirit and can do a little change, therefore protection range of the present utility model must be as the criterion with its claim.
