Title:
BIDIRECTIONAL UNIFORM RADIATION ANTENNA FEED SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/041576
Kind Code:
A1
Abstract:
The present application relates to a bidirectional uniform radiation antenna feed system, comprising a power division feed network (201) and multiple waveguide slot antenna arrays (118). The multiple waveguide slot antenna arrays (118) are equally divided into two superimposed groups; each of the waveguide slot antenna arrays (118) comprises eight waveguide slot antennas (402); the waveguide slot antennas (402) are placed on a first power divider (505) of the power division feed network (201); the waveguide slot antennas (402) on the two superimposed waveguide slot antenna arrays (118) are arranged in a staggered manner. Bidirectional radiation is adopted in the present invention, i.e., the top and the bottom are each provided with 32 waveguide slot antennas which irradiate to the middle, and radiation electromagnetic fields are evenly distributed, such that radiation blind areas are effectively reduced; moreover, the waveguide slot antennas adopt a standing wave array antenna form, the length of the radiation electromagnetic fields is evenly distributed along the antenna direction, and two adjacent waveguide slot antennas are fed by different frequency sources, with slots thereof staggered to each other, such that the electromagnetic field superposition is effectively reduced.
