Abstract

The invention relates to a ridge waveguide bias slot coupling micro-strip oscillator dual polarized antenna. The antenna comprises two parallel arranged ridge waveguide bias slot coupling micro-strip oscillator dual polarized antenna units, more than two positive metal pasters and more than two negative metal pasters, wherein the positive metal pasters and the negative metal pasters are uniformly arranged on the outer side face of a micro-strip plate. Centers of the positive metal pasters correspond to more than two radiation seams on a first radiating waveguide. Centers of the negative metal pasters correspond to more than two radiation seams on a second radiation waveguide. The positive metal pasters and the negative metal pasters are coupling micro-strip oscillators, thereby achieving dual polarization. According to the invention, a ridge waveguide structure is adopted, thereby achieving dual polarization and low profiles; I-shaped coupling seams are used for direct coupling feeding, thereby achieving integrated design of antennas and feeder lines; and the antennas can freely from large plane arrays as units.

Description

technical field [0001] The invention belongs to the technical field of panel antennas, and in particular relates to a ridge waveguide offset slot coupled microstrip dipole dual-polarization antenna. Background technique [0002] Array antennas are widely used in mobile communication fields such as airborne, ship-borne, and vehicle-mounted. Compared with reflector antennas, array antennas can conveniently achieve a low profile and have higher efficiency. Today, with the further development of the manufacturing process, the price of the array antenna has been greatly reduced, but it is still higher than that of the reflector antenna, especially the price of the dual-polarized panel antenna is higher. At present, the existing solutions are similar to the horn array antenna in the field of communication in motion, full waveguide structure, wide bandwidth, high efficiency, dual polarization oblique beam waveguide slot array antenna, using two different structures of slot travelin...
