Abstract

The invention belongs to the technical field of wireless communication and in particular relates to an antenna radio frequency front end device with direction finding and initiative anti-interferencefunctions. The device comprises four transceiving channel circuits, four antennae and one regular tetrahedron frame structure, wherein each antenna is connected with one transceiving channel circuit and is arranged at one vertex position of the regular tetrahedron frame structure. Regular tetrahedron three-dimensional layout at the antenna radio frequency front end can minimize structure size andrear-end signal processing can be combined for accurately learning positions of a useful signal and an interference signal in the space, so as to realize the directional communication and anti-interference aims. The device provided by the invention also can specifically reduce amplitude of the interference signal by applying an arranged radio frequency sum and difference channel, so that linear dynamic range of a receiver and signal-to-noise ratio of a system are increased.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and in particular relates to an antenna radio frequency front-end device with functions of direction finding and active anti-jamming. Background technique

[0002] As we all know, today's spectrum resources are getting tighter and tighter. Applications such as radio and television, communications, and radar occupy most of the frequency bands within 6GHz, and microwave and millimeter wave spectrum resources with higher frequencies are actively being developed. Therefore, for a specific application, there is potential for more and more radio interference. In order to meet this challenge, in addition to the reasonable planning of spectrum resources by the international community and domestic authorities, various device manufacturers are also working hard to develop analog filters with good suppression performance, small size, and low insertion loss. For example, base stations in publ...
