Problems solved by technology

[0003] However, since the transmission phase shift provided by the frequency selective surface unit is much smaller than 360 degrees under the limitation of the transmission amplitude of 3dB, the traditional dual-polarization transmission array antenna usually needs to use a multi-layer frequency with more than three layers of dielectric plates. Selecting the structure as the array unit greatly increases the complexity of manufacturing the dual-polarization planar transmission array antenna, which leads to an increase in manufacturing costs
So far, there has been no related technology to realize dual-polarized transmissive array antennas on a single-layer microstrip

Abstract

The invention discloses a single-layer microstrip dual-polarization transmission array antenna and a manufacturing method. The antenna is composed of a horn feed source and a Huygens metasurface microstrip dual-polarization transmission array. The horn feed source is composed of a waveguide and a horn opening, and the Huygens metasurface microstrip dual-polarization transmission array is composedof N * N metasurface transmission units. The metasurface transmission unit is composed of two layers of composite metal structures with biaxial symmetry on an xy plane and a single-layer dielectric plate, and the composite metal structure on the upper layer is formed by opening gaps on four sides of a square metal frame, and the composite metal structure on the lower layer is formed by removing four corners on a square metal frame. The dual-polarization transmission array antenna is manufactured based on a single-layer dielectric plate, through holes do not need to be punched, and the performance of the dual-polarization transmission array antenna meets the beneficial effects of low sidelobe, high gain, high aperture efficiency, enough bandwidth and the like, so that the dual-polarizationtransmission array antenna is easier to manufacture, lower in cost and easier to assemble and integrate under the condition that the same performance of a traditional transmission array antenna is achieved.

Description

technical field [0001] The invention belongs to the field of single-layer microstrip dual-polarization transmission array antennas, in particular to a single-layer microstrip dual-polarization transmission array antenna based on Huygens metasurface and a manufacturing method. Background technique [0002] The planar transmission array antenna is a new type of array antenna that combines the advantages of the traditional parabolic antenna and the microstrip array antenna. Among them, the dual-polarized planar transmission array antenna can integrate two antennas with mutually orthogonal polarization directions, and work in the duplex mode of transmitting and receiving at the same time, so its most prominent advantage is to save the number of antennas for a single directional base station. Due to its planar configuration, it has the advantages of small size, light weight, low manufacturing cost, and easy integration. Dual-polarized planar transmission array antennas have been ...
