Abstract

The invention discloses a dual-magnetic-moment antenna. The dual-magnetic-moment antenna comprises a first substrate, a signal feed-in line, a main dual-magnetic-moment antenna, an auxiliary antenna and a liquid crystal layer. The first substrate comprises a first surface and a second surface. The signal feed-in line is arranged on the first surface, the main double-magnetic-moment antenna and the auxiliary antenna are arranged on the second surface, the main double-magnetic-moment antenna and the signal feed-in line are overlapped, and the auxiliary antenna and the main double-magnetic-moment antenna are arranged in series and located in the direction, facing the tail end of the feed-in line, of the main double-magnetic-moment antenna. The liquid crystal layer is arranged on the main double-magnetic-moment antenna and the auxiliary antenna.

Description

technical field [0001] The invention relates to a dual magnetic moment antenna, in particular to a dual magnetic moment antenna which improves forward radiation energy and reduces back radiation energy. Background technique [0002] The planar antenna adopts an electronic non-mechanical rotating beam scanning method, which has the advantages of high stability, beam gain increases with the number of antenna elements, and small size and high integration. It can be applied in millimeter wave radar of automatic driving assistance system, automatic navigation outside the line of sight of unmanned aerial vehicle, satellite positioning and navigation system, wireless communication area network system, remote monitoring of physiological characteristics, wireless power transmission and fifth-generation mobile communication, etc. in the field. [0003] The antenna unit of the planar antenna mainly uses a medium with adjustable dielectric coefficient filled around the electrode, such ...
