Abstract

The invention relates to a Ka-band broadband low-profile dual-line polarized microstrip antenna based on high-frequency lamination technology. The feeding structure consists of an octagonal floor coupling cavity, a stripline dual-polarization feeder, and a metallized feeding via hole. and the metal floor circular opening together, the stripline dual-polarized feeder terminal is a gradual coupling end, forming a multi-resonant multi-layer coupling structure with the octagonal floor coupling cavity; the metallized feed-through hole passes through the multi-layer high-frequency The circular opening on the dielectric board and the inner metal floor transmits the signal vertically from the stripline layer to the bottom of the antenna; the inner conductor of the SSMP connector is inserted into the metallized feeding via hole, and the outer conductor is welded to the underlying metal floor to This serves as the external electrical interface of the antenna. The antenna has a compact structure, small size, easy integration, low cost, and low processing difficulty. While working in a wide frequency band, it has dual-linear polarization radiation characteristics and can meet the application requirements of Ka-band broadband phased array systems or communication systems.

Description

technical field [0001] The invention relates to a Ka-band broadband low-profile dual-line polarized microstrip antenna based on high-frequency lamination technology, which can be used as a radiation unit of a Ka-band broadband phased array system and belongs to the technical field of wireless communication system antennas. Background technique [0002] With the rapid development and application of 5G communication and millimeter-wave sensor systems, millimeter-wave active phased arrays with fast beam-scanning and broadband coverage characteristics will become the main choice of hardware solutions. The overall performance of the active phased array system is inseparable from the characteristics of the selected antenna radiation unit: first, the matching and coupling characteristics of the unit determine the coverage of the working frequency band of the array; the lateral size of the unit determines the scanning of the array in the working frequency band Coverage; the polariza...
