- the invention relates to a dielectric resonator antenna (DRA) with an electrical conductive layer in a plane of symmetry.
- DRA dielectric resonator antenna
- the invention also relates to a transmitter and receiver with a dielectric resonator antenna with an electrically conductive layer in a plane of symmetry and on a mobile device with such an antenna.
- Dielectric resonator antennas are known as miniaturized antennas made of ceramic or another dielectric for microwave frequencies.
- a dielectric resonator the dielectric of which is surrounded by air with a dielectric constant of ⁇ r >> 1, this has a discrete spectrum of natural frequencies and natural modes.
- the radiation of power is in the foreground with a resonator antenna. Since no conductive structures are used as the radiating element, the skin effect cannot have a negative effect. Such antennas therefore have low ohmic losses at high frequencies.
- a compact, miniaturized structure can also be achieved.
- Such a DR antenna 1 is shown in FIG. 1 in the basic form considered as an example.
- other shapes are also possible, such as cylindrical or spherical geometries.
- Dielectric resonator antennas are resonant components that only work in a narrow band around one of their resonance frequencies. The problem of antenna miniaturization is equivalent to lowering the working frequency for given antenna dimensions. Therefore the lowest resonance (TE z 111 mode) is used. This mode has a plane in which the tangential component of the electric field disappears, which is called plane of symmetry 2.
- the resonance frequency remains the same as that of an antenna with the original dimensions. This is shown in Figure 2.
- a further miniaturization can be achieved with this antenna by means of a dielectric with a high dielectric constant ⁇ r .
- a material with low dielectric losses is preferably selected.
- dielectric resonator antenna Such a dielectric resonator antenna is described in the article "Dielectric Resonator Antennas - A review and general design relations for resonant frequency and bandwidth", Rajesh K. Mongia and Prakash Barthia, Intern. Journal of Microwave and Millimeterwave Computer-aided Engineering, Vol. 4, No. 3, 1994, pages 230-247.
- a cuboid dielectric resonator antenna is described in particular in FIG. 9 and the associated description.
- the original structure can be halved without changing the field distribution or other resonance characteristics for the Te z 111 mode (page 244, right column, Lines 1-7).
- the DRA is excited via a feed line with microwave power by being introduced into the stray field in the vicinity of a microwave line (for example a microstrip line or the end of a coaxial line).
- An antenna is known from EP 0 790 663 A, which uses the known SMD technology (Soldering on the surface of the board) is mounted on a circuit board (PCB).
- the antenna consists of a dielectric or magnetic substrate and has two Radiation electrodes, one of which is a radiation electrode Generated resonance frequency. Another connected to a feed line Electrode is on an opposite surface of the substrate. A there is another electrode connected to a ground potential on the back of the substrate. The two radiation electrodes are connected to the ground potential and each have an open end. The open ends of the radiation electrodes and the Electrode connected to the lead are electromagnetic through a gap between a radiation electrode and the electrode connected to the feed capacitively coupled. A wide range can be achieved through the antenna, in the signals of two different frequencies without reducing the Gain and without increasing the antenna configuration received and can be sent. Furthermore, a telecommunications device with a such antenna disclosed.
- 3b and 5b each show a dielectric resonator antenna with a Microstrip line as supply line.
- the resonator antenna shown in FIG. 3b stands out with a right-angled notch on the underside.

- a metal layer for forming the provided electrically conductive layer in the plane of symmetry and the electrical contact are suitable due to their good manufacturing properties and electrical conductivity good for realizing the connection with a supply line.
- a metal layer is on a plane of symmetry adjacent side of the DRA for connection to the electrical contact in the Plane of symmetry provided.
- a cuboid antenna with the plane of symmetry as Base of the electrical contact can be attached to an adjacent end face.
- the metal layer is carried over the edge to the base, so that in a plane of symmetry is created on the plane of symmetry, which is used for surface mounting can be.
- This soldering point is of course isolated from the electrically conductive layer, which is preferably done by leaving out a small area when metallizing the plane of symmetry happens.
- a silver paste is advantageously used to form the metal layer provided by burning into the material of the DRA.
- the material for the dielectric resonator antenna is a ceramic made of (Ba, Nd, Gd) TiO3 is provided. This ceramic material shows everyone important properties for the dielectric resonator antenna such as high dielectric constant, low dielectric losses and a low dielectric temperature coefficient on.
- the object of the invention is achieved by a transmitter and a receiver as well as a mobile radio device in which at least in the plane of symmetry of the antenna an electrical contact which is insulated from the electrically conductive layer is provided, and the electrical layer and the electrical contact for connecting the dielectric Resonator antenna with at least one feed line for one to be transmitted or received Signal are provided.
- FIG. 3 shows a dielectric resonator antenna (DRA) 4 with a metallic layer 5 in a plane of symmetry. Furthermore, the ceramic cuboid of the DRA 4 has a second metallization 6 on one end face. The second metallization 6 has a soldering point 7, which is electrically insulated from the metal layer 5 in the plane of symmetry. The solder point 7 forms the additional electrical contact in the plane of symmetry.
- the plane of symmetry in which the tangential component of the electric field of the desired eigenmode (lowest resonance in TE z 111 mode) disappears is provided with a metallization firmly connected to the dielectric. This is preferably done with a silver paste that is burned into the ceramic.
- the second metallization 6 on the end face is applied in the same way.
- These metallizations 5, 6, 7 allow surface mounting (surface mount device, SMD), that is, the flat soldering of electronic components on a printed circuit board (printed circuit board PCB) by means of a wave solder bath or a reflow process.
