Embodiments of the present invention provide a dual circularly polarized antenna unit and a dual circularly polarized front antenna, which relate to the field of antenna technology. The dual circularly polarized antenna unit includes a first radio frequency microwave board, a second radio frequency microwave board, a dual Circular pole bridge and radiation patch, the present invention adopts the structure of multilayer board with metal vias, realizes the planar double circular polarization function of the multilayer board structure, and sets the double circular pole bridge and radiation patch respectively on the At the same time, the quasi-coaxial structure of the input end is achieved by drilling holes on the first radio frequency microwave board, which breaks through the technological limitations and makes the drilling method available in the Ka and above frequency bands, which meets the technological requirements and simplifies the process. structure, which solves the feeding problem.
Description
Dual circularly polarized antenna elements and dual circularly polarized front antennas technical field The present invention relates to antenna technology field, specifically, relate to a kind of double circularly polarized antenna unit and double circularly polarized array surface antenna. Background technique [0002] As the requirements of the communication system for signal bandwidth and signal rate gradually increase, the requirements for terminal antennas are also increasing. higher. Replacing traditional parabolic antennas with low-cost phased array antennas has recently shown great advantages, but phased array antennas have The performance drops more on large-angle scanning, which has a great impact on the overall usage. [0003] Tightly coupled antennas are an effective measure to solve the degradation of large-angle scanning performance. Most of the current tightly coupled antennas Only single-line polarization or dual-line polarization is studied, while c...
