Title:
LEAKAGE WAVE MICROSTRIP ANNULAR ORBIT ANGULAR MOMENTUM ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/156253
Kind Code:
A1
Abstract:
Provided is a leakage wave microstrip annular orbit angular momentum antenna. The antenna comprises a dielectric substrate, microstrip lines and a ground plane respectively arranged on an upper surface and a lower surface of the dielectric substrate, wherein the microstrip lines comprise a plurality of annular microstrip lines concentrically arranged at intervals, the plurality of annular microstrip lines are provided with openings so that a starting end and a termination end of each annular microstrip line are formed at each opening, the starting end is connected to a coaxial feeder for connecting to a feeding network, and the termination end is connected to a matched load. The openings are provided in the microstrip lines, and opening ends of the microstrip lines are connected to the matched loads, so that the antenna generates an annular traveling wave to radiate OAM; and by arranging at least two concentric microstrip lines on the dielectric substrate 1, the antenna integrates at least two independent microstrip radiation units, so that integration of a plurality of OAM mode radiation units at the same working frequency is achieved, thereby making the antenna more practical.
