Description

technical field [0001] The invention relates to an end-fire multi-beam dual circularly polarized antenna array adopting medium-loaded stepped slots with wide application prospects, and belongs to the technical field of antennas. Background technique [0002] Antennas are an important part of wireless communication systems. The rapid development of wireless communication creates an urgent need for low-profile, multi-beam, high-gain, multi-polarization, low-cost and easy-to-integrate antennas. [0003] The circularly polarized antenna can receive any polarized electromagnetic wave from any antenna, which can effectively improve the receiving and radiation efficiency, so it is widely used in actual jamming and electronic reconnaissance. Circularly polarized antennas can be implemented in various antenna forms such as horn antennas, microstrip antennas, or cavity-backed antennas. [0004] The traditional planar multi-beam antenna array design focuses more on linear polarizatio...
