Problems solved by technology

[0003] At present, phased array antennas are widely used in millimeter-wave radar and wireless communication. Phased array technology promotes the development of phased array antennas. Microstrip phased array antennas have a ground profile, low cost, light weight, easy processing and convenient Advantages such as installation, however, due to the narrow bandwidth defect of microstrip phased array antenna, it cannot be used in wide bandwidth RF system

Abstract

The invention provides a microstrip phased-array antenna unit and an array thereof, the unit comprises a radiation structure, a feed structure and an SIW back cavity, the radiation structure comprises a first dielectric layer, a second dielectric layer and a radiation patch, the radiation patch is located on the upper surface of the first dielectric layer, the second dielectric layer is located below the first dielectric layer, the feed structure comprises a third dielectric layer, a fourth dielectric layer and a grounding plate, the grounding plate is located between the second dielectric layer and the third dielectric layer, the grounding plate is provided with a coupling gap of a spindle-shaped structure, the coupling gap is correspondingly arranged under the radiation patch, and the feed structure couples energy of the microstrip feed line to the radiation patch through the coupling gap; and an SIW back cavity with a back cavity structure is formed on the first dielectric layer, the second dielectric layer, the third dielectric layer and the fourth dielectric layer along the periphery of the radiation patch through the metal via holes, so that the antenna has the characteristics of wide bandwidth, low cost and low profile through the structure, the radiation efficiency of the antenna is also improved, and mutual coupling is reduced.

Description

Technical field [0001] The present invention relates to the technical field of microwave antennas, and particularly to a phased array antenna elements and a microstrip array. Background technique [0002] The antenna front-end wireless communication system, is used to transmit or receive electromagnetic waves device. In recent years, the development of communication technologies on the performance of the antenna put forward higher requirements. Phased-array antennas by the array of antenna elements arranged in a specific manner by, for each cell to be phase by an appropriate shift (or delay) to obtain the beam deflection array, to achieve rapid scanning beam, multi-beam scanning and a flexible beam pointing. [0003] Currently, the phased array antenna is widely used in wireless communications and millimeter wave radar, phased array antenna of the phased development, microstrip phased array antenna having the cross-section, light cost, quality, ease of processing and ease of inst...
