Abstract
The present application discloses a circularly polarized waveguide array antenna, a double circularly polarized waveguide array antenna and a manufacturing method thereof. The present application mainly arranges sequentially arranged circularly polarized slot structures on the upper metal surface of the substrate integrated waveguide. Wherein, each circularly polarized slot structure includes two offset oblique slots forming an angle with each other. Using the circularly polarized slot structure, circularly polarized waves are generated when electromagnetic waves are fed in, so that a single circular pole can be formed separately. Polarized waveguide array antennas or combined to form dual circularly polarized waveguide array antennas. This type of antenna has a simple structure and high work efficiency, and is suitable for millimeter wave communication application scenarios.
Description
technical field [0001] The present application relates to circularly polarized waveguide array antenna technology, in particular to a (dual) circularly polarized waveguide array antenna which works in the atmospheric window frequency band and can generate (dual) circularly polarized waves and a manufacturing method thereof. Background technique [0002] A circularly polarized wave refers to a radiation wave in which the track of the radiation electric field of the antenna rotates on a circle with time as viewed along the propagation direction. Circularly polarized waves are relative to linearly polarized waves, which mean that the electric field changes along a line with time. Compared with linearly polarized waves, circularly polarized waves have obvious advantages. Antennas in circularly polarized transceiver systems no longer require polarization alignment and polarization matching like linearly polarized antennas, otherwise signal transmission will not be possible.
