Embodiment Construction

[0023] refer to figure 1 The dielectric rod horn antenna feed source invented in this paper consists of a tapered dielectric rod 1, a conical horn radiation port 2, a plastic screw 3, a circular waveguide 4, a transmitting SMA connector 5, a metal reflection rod 6, and a receiving SMA connector 7. Wherein, the tapered dielectric rod 1 inserted into the radiation port 2 of the conical horn is fixed by a plastic screw 3 . The transmitting SMA connector 5 and the receiving SMA connector 7 adopt 50 ohm SMA connectors often used in microwave communication, which can be directly connected to the signal generator or receiver; the metal reflective rod 6 is fixed in the circular waveguide 4 by welding or drilling.

[0024] The present invention works in the Ku band, and the transmitting SMA connector 5 is used for transmitting the frequency band f T (bandwidth 5%), receiving SMA connector 7 for receiving frequency band f R (Bandwidth 5%). Adjust the position of launching SMA joint 5,...

Abstract

The invention provides a transmit-receive dual-polarized and dual-band feed source for a parabolic antenna system, a luneberg lens antenna system and the like in satellite communication. The feed source works at Ku band, has a rotational symmetric directional diagram with adjustable lobe width, a cross polarization level which is less than -35dB, high radiation performance such as return loss and transmit-receive isolation, has a simple, small and exquisite structure and high practicality, and can flexibly meet different requirements of different antenna systems.

Description

technical field [0001] The invention belongs to the technical field of feed source design in wireless communication, and particularly relates to technologies such as dual frequency bands, dual polarization, and low cross polarization for feed source design in satellite communication systems. Background technique [0002] With the development of satellite communications, the existing C-band satellite resources can no longer meet the growing demand for satellite communications, so it is imperative to develop Ku and Ka bands. The vigorous development of the satellite communication business puts forward new requirements for its ground station antenna, such as high gain, broadband or multi-band, low cross-polarization, multi-beam, dual-polarization or multi-polarization, etc. The feed source is the entire antenna The heart of the system, a high-performance feed is the first condition for a high-performance system. How to design feeds that work in broadband or multi-bands in the ...
