Communication and navigation integrated integration antenna

Abstract

The invention discloses a communication and navigation integrated integration antenna, and belongs to the technical field of microwave array antennas. The invention proposes an integrated design of anantenna unit and a network, physically adopts a multi-layer plate crimping technology to integrate the radio frequency and a digital circuit, perform the aperiodic arrangement of the antenna unit ofthe satellite communication and rotate the feeding to improve the axial ratio of the antenna. In the gap between the antenna units, a series of antennas for satellite navigation, including an L-band anti-jamming receiving antenna, a Beidou antenna, a Beidou directional antenna and a short message service antenna, are fully utilized, so that the functional diversification of the system design is fully considered, and the S-band satellite communication phased array antenna is laid out, and the navigation antenna is decomposed and designed to simplify the design difficulty. The communication andnavigation integrated integration antenna is applicable to various platforms, can be used as an antenna for satellite communication and satellite navigation combination, and is particularly suitable for occasions where the installation space of the platform is limited but the type of the antenna is required.

Description

technical field [0001] The invention relates to the technical field of microwave array antennas, in particular to a communication and navigation integrated integrated antenna. Background technique [0002] At present, common communication and navigation antennas mainly have the following combinations: [0003] 1. The communication antenna and the navigation antenna are set separately. The idea of ​​this design form is relatively simple and easy to implement. It has the characteristics of independent structure, independent function, and independent interface. However, this type of scheme has high requirements for space, and each antenna needs to be equipped with its own information processing equipment. [0004] 2. The antenna type of communication antenna and navigation antenna adopts omnidirectional antenna. This form requires a smaller volume of the antenna, and each pair of antennas occupies less space. However, the signal strength of this type of antenna is low, and it...

AI Technical Summary

Problems solved by technology

However, the isolation between the antennas is poor, especially for occasions where the frequency bands are not much different, the electromagnetic compatibility of this combination deteriorates very obviously

[0006] In short, there are various problems in the various communication and navigation antenna combination forms in the prior art, and there is still room for improvement
