Problems solved by technology

However, since the frequency selective surface unit can provide a transmission phase transformation much smaller than 360 degrees under the limitation of the transmission amplitude of 3dB, the traditional transmission array antenna usually needs to use a multilayer frequency selective structure with more than three layers of dielectric plates as Array unit, which greatly increases the complexity of the planar transmission array antenna manufacturing, resulting in an increase in manufacturing costs

Abstract

The invention provides a single-layer microstrip transmission array antenna based on a Huygens meta-surface and a manufacturing method thereof. The single-layer microstrip transmission array antenna is composed of a horn feed source and a Huygens meta-surface microstrip transmission array. The horn feed source is composed of a waveguide and a horn opening. The Huygens meta-surface microstrip transmission array is composed of N*N meta-surface transmission units. Each super-surface transmission unit is composed of two layers of composite metal structures symmetrical about the x-axis and a singlelayer of dielectric plate, wherein the upper layer composite metal structure is composed of two interconnected concentric arcs, and the opening of the concentric arc is upward; the lower layer composite metal structure is symmetrical with the upper layer composite metal structure about the x-axis, and the concentric arc opening of the lower layer composite metal structure is downward; the outer arcs of the upper and lower composite metal structures have an overlapping region. The single-layer microstrip transmission array antenna has the beneficial effects of low sidelobe, high gain, single-layer dielectric plate design, no through hole, low weight, low cost and easy assembling and integration.

Description

technical field [0001] The invention relates to the technical field of microstrip transmission array antennas, in particular to a single-layer microstrip transmission array antenna based on a 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. Due to its planar configuration, it has the advantages of small size, light weight, low manufacturing cost, and easy integration, and has been widely used in wireless communication systems and satellite communication systems. The planar transmission array antenna consists of a planar transmission array and a feed antenna. The planar transmission array is a topological combination of transmission-type frequency-selective surface units, and each array unit provides corresponding phase compensation to generate the required high-directional transm...
