Abstract
The utility model provides a double-wave beam aerial, which is characterized in that the utility model comprises a loudspeaker feed source and a waveguide exciter, wherein, the loudspeaker feed source is fixedly connected with the waveguide exciter into integration through a waveguide transformer. The utility model can simultaneously receive and emit horizontal and vertical polarized wave beam signals; therefore, the utility model is suitable for an earth station antenna of a satellite to simultaneously receive double-wave beam satellitic signals (such as the Asia satellite 1); besides, the utility model is suitable for simultaneously receiving wave beam signals of two different polarized satellites or used for receiving and emitting two wave beam signals.
Description
The utility model provides the two-beam antenna of a kind of reception simultaneously and emission level and perpendicular polarization wave beam signal.
The simple beam antenna, for example the jam lattice of the satellite ground reception antenna of being sold on the market, guided missile tracking can antenna, the height-finding radar antenna, microwave radio relay communication antenna etc. all can only receive the signal of simple beam satellite, can not receive the signal of two satellites of different polarization simultaneously, can not transmit and receive the signal of two wave beams, so function singleness, the scope of application is restricted.
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of two-beam antenna is provided.
The utility model provides a kind of two-beam antenna, comprises horn feed and waveguide excitation device, and horn feed and waveguide excitation device are fixed with one by waveguide transformer.
Above-mentioned waveguide transformer comprises the cylindrical shape inverter body, have on the top of cylindrical shape inverter body and to be the ring flange of one with it, Connection Block formed integrally therewith is arranged on the left side wall of cylindrical shape inverter body, and the middle part of Connection Block has the hole of dress insulated tube and excitation probe.
Above-mentioned horn feed is the convex edge loudspeaker, also can be conical horn, corrugated horn or pyramid loudspeaker etc., the convex edge loudspeaker are made of circular waveguide mouth and cylindrical shape waveguide formed integrally therewith, the annular ripple groove is arranged in the cylindrical shape waveguide, the convex edge loudspeaker are sleeved on the waveguide transformer bottom, and fixedly connected with it, can adopt bolt or other connector to connect.The convex edge loudspeaker can produce the directional diagram of requirement, gain and standing-wave ratio.The H11 ripple that produces in the loudspeaker circular waveguide of convex edge is converted to TE10 ripple in the rectangular waveguide by waveguide transformer.
Above-mentioned waveguide excitation device is made of excitation body and ring flange formed integrally therewith, fixedly connected with the Connection Block on the waveguide transformer in the bottom of excitation body, but bolt connects or adopt alternate manner to connect, excitation body upper and lower has the corresponding hole of perforate with Connection Block middle part institute, excitation probe is arranged in the hole, the bottom of excitation probe is passed Connection Block middle part institute's perforate and is placed in the waveguide transformer, by the insulated tube insulation, there is the lid of fixedlying connected with the excitation body upper end of insulated tube between excitation probe and the exciter.The waveguide excitation device realizes that the rectangular waveguide underexcitation goes out the TE10 ripple.
The utility model is be combined as a whole the just signal of reception simultaneously and emission level and perpendicular polarization wave beam of convex edge loudspeaker and waveguide excitation device.
The utility model is applicable to that the satellite ground station antenna receives the signal of dualbeam satellite (as the Asiasat 1 satellite) simultaneously; Also be applicable to the beam signal that receives two satellites of different polarization simultaneously, or be used to transmit and receive two beam signals.The function of two kinds of simple beam antennas of the utility model collection is an one, has dual-use function, and antenna pattern etc. changes good characteristics, and unreal is a kind of desirable two-beam antenna.
