The conventional method for realizing bidirectional radiation antenna is that two one-way radiation devices are arranged back-to-back, are respectively directed to two
Opposite direction is (referring to L. Liu, Z. Zhang, Z. Tian, and Z. Feng, " A bidirectional end
re array with compact antenna elements for coal mine/tunnel communication,”
IEEE Antennas Wireless Propat. Lett., vol. 11, pp. 342-345,2012.).This method needs
Configure two one-way radiation devices.The bidirectional radiation antenna that this method is realized, it usually needs increasing additional match circuit could be same
When match two one-way radiation devices, will increase the complexity of antenna in this way.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of bidirectional radiation medium resonator antenna, which has knot
Structure is simple, small in size and the advantages that without increasing match circuit.
The present invention adopts the following technical scheme that:
A kind of bidirectional radiation medium resonator antenna, including two materials and the identical dielectric resonator of outer dimension, one
Bottom plate, a via hole, a SMA connector and a feed probes；The baseboard material is metal, and cross section is circle；The via hole
For circular through hole, positioned at the center of the bottom plate；The SMA connector is fixed on the lower surface of base plate center；
The feed probes material is metal, and shape is thin cylinder, and one end is connected with the SMA connector, and the other end passes through
The via hole, and upwardly extend；Adjust the bidirectional radiation dielectric resonance that the length of the feed probes can be such that the present invention designs
Device antenna reaches matching status；Two dielectric resonators are the radiator of inventive antenna, and material is ceramic Jie
Matter, shape are cylindrical body；Described two dielectric resonators are placed in the plate upper surface, and respectively with the feed
Probe fits；Described two dielectric resonators are symmetrically placed about the feed probes.
Compared with prior art, the present invention having substantive distinguishing features and remarkable advantage following prominent:
