Description
Technical field
The present invention relates to communication equipment field, be specially a kind of satellite feed assembly.
Background technology
In the communications field of satellite, feed, as the primary radiator of antenna, is the heart of antenna, is the parts of not staying or lacking.Its effect arranges the electromagnetic wave come through reflective surface, makes its polarised direction consistent.And carry out impedance transformation, make the electromagnetic waveform propagated by circular waveguide in feed become the electromagnetic wave propagated by rectangular waveguide in tuner, thus improve the efficiency of antenna.And along with the development of science and technology, miniaturized and high precision int is the trend that feed assembly develops.But along with the high speed development of the communication technology, satellite communication capacity height increases rapidly, the satellite antenna weight of present stage is common is greater than 30KG, be difficult to realize individual soldier's load, and often need feed assembly to have the ability of transmit-receive sharing and polarization utilization simultaneously, also to ensure the performance requirements such as its electrical property, weight, volume simultaneously, must improve from the various aspects of antenna.Feed assembly is the important step ensureing antenna performance, reduces its volume, can cause very large impact to electrical property, and arrange performance severe exacerbation, particularly transmitting terminal standing wave worsens comparatively large, is unfavorable for the use in high-power situation, finally causes the service life reduction of feed.Therefore, while guaranteed performance, reduce the important topic that its weight and volume is the development of feed assembly.
For the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
