Integrated six-frequency-range multipurpose composite feed source

Abstract

The invention provides an integrated six-frequency-range multipurpose composite feed source. The feed source comprises four reflecting plates, L / S oscillators, four X frequency range loudspeakers and a Ku / K / Ka frequency range loudspeaker, wherein the four X frequency range loudspeakers are arranged symmetrically by taking a visual axis of an antenna as the center, the Ku / K / Ka frequency range loudspeaker is embedded to the symmetrical center of the four X frequency range loudspeakers and shares loudspeaker walls with the X frequency range loudspeakers, the four reflecting plate is arranged in the surrounding of the X frequency range loudspeakers, a plane where the central axes of two adjacent X frequency range loudspeakers are placed is parallel with corresponding reflecting plate, the L / S oscillators are vertically mounted on the reflecting plates respectively, and the length of the L / S oscillator in the direction vertical to the reflecting plate is 22-26mm.

Description

technical field

[0001] The invention relates to the technical field of reflector antennas, in particular to an integrated six-band multi-purpose composite feed source. Background technique

[0002] The antenna feed refers to the primary radiator of the continuous aperture antenna or antenna array. The corrugated horn is widely used because of its good symmetry of the pattern, low side lobes, and wide frequency band.

[0003] Due to the need for automatic tracking, there are usually combined horns. Set four identical horns symmetrically around the antenna boresight as the center, and use them simultaneously for receiving and sending communications. The sum of the signal amplitudes received by the four horns is called the sum signal (that is, the main beam of the antenna, "the sum beam"), which is received by the left and right horns. The difference between the amplitude values ​​is called the azimuth angle difference signal, and the difference between the amplitude values ​​...
