Description
[technical field]
The utility model relates to the antenna of mobile communication base station field, relates in particular to broadband dual polarized antenna a period of time and radiating element thereof.
[background technology]
Along with the development of mobile communication technology, also more and more higher to the requirement of antenna for base station.Antenna for base station generally is combined into array format by identic radiating element, to obtain high gain.The gain of radiating element, front and back ratio, intermodulation, cross polarization such as compare at indexs such as gain that performance will directly have influence on entire antenna, cross polarization ratio, front and back ratio, intermodulation.At present, a period of time of dual polarized antenna half-wave dipole structures that adopt two pairs of quadratures add supporting seat with radiation fin and form more, perhaps adopt the double dipole of two secondary quadratures to form.Traditional horizontal half-power beam angle is 65 ° a dual polarized antenna, and single a period of time can't accomplish more than the 10dBi, and feeding classification employing direct feed, and the intermodulation characteristic is relatively poor, can not satisfy the needs of mobile communication development.
[summary of the invention]
The technical problems to be solved in the utility model provide a kind of have high-gain, high before and after ratio, broadband dual polarized antenna a period of time of good intermodulation characteristic.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of wideband high-gain aerial a period of time, comprise radiating element, feed tab, reflecting plate, described radiating element comprises radiant panel and leg, and the lower end of described leg is fixed on the reflecting plate, described radiant panel and leg are one and are bent into 90 ° mutually, the gabarit of radiant panel is the rectangle of corner cut, and in the bending place of radiant panel and leg, a dihedral of radiant panel rectangle gabarit becomes incisal angle edge; Described radiant panel has polygonal endoporus; Described radiating element is 8, and the radiating element of per 2 shape symmetries constitutes 1 half-wave dipole, and 4 half-wave dipoles are placed with the orthogonal manner symmetry, and the leg of adjacent half-wave dipole is relative, is connected by feed tab between the adjacent leg.
In above-described wideband high-gain aerial a period of time, described rectangle is a square.Described polygonal endoporus and radiant panel gabarit form wide periphery.The angle of cut on the pairwise orthogonal limit of described incisal angle edge and radiant panel respectively is 135 °.
In above-described wideband high-gain aerial a period of time, described feed tab adopts coupled structure, and the both sides of feed tab are individually fixed on the leg of 2 radiating elements with working of plastics.
Radiating element of the present utility model is all made by a sheet metal, is one, does not have segmentation, has so just reduced nonlinear contact, thereby improves the intermodulation characteristic.In addition, 4 half-wave dipoles of the utility model have more significantly effect in the lifting of gain, also brought high front and back ratio simultaneously.So the utility model is a kind of have high-gain (single a period of time gain can reach more than the 11dBi) and high front and back ratio, good intermodulation characteristic is simple in structure, the broadband dual polarized antenna a period of time that is easy to produce.
