Problems solved by technology

[0004] However, due to the defects of narrow beam width, narrow bandwidth, small gain, and low radiation efficiency, the traditional microstrip antenna is limited in many applications.
Especially at the receiving end of wireless energy transmission, the antenna is required to have higher effective receiving energy in a wider direction, and traditional antennas are more limited in this case

Abstract

The invention relates to a wide-beam dual-polarized micro-strip antenna which comprises a main radiation chip, a substrate, a ground plane and a coaxial feed conductor probe. The main radiation chip is arranged above the substrate. The ground plane is arranged on the bottom surface of the substrate. One end of the coaxial feed conductor probe is connected with the main radiation chip. The other end of the coaxial feed conductor probe is connected with the ground plane after passing through the substrate. The wide-beam dual-polarized micro-strip antenna further comprises a first parasitic radiation chip and a second parasitic radiation chip which are disposed above the substrate. The first parasitic radiation chip and the second parasitic radiation chip form a central angle of 90 degrees by using the main radiation chip as a center of circle. The main radiation chip, the first parasitic radiation chip, the second parasitic radiation chip are provided with short-circuit walls. The short-circuit wall comprises at least 8 short-circuit pins. One end of each short-circuit pin of the short-circuit wall is connected with the main radiation chip, the first parasitic radiation chip, and the second parasitic radiation chip. The other end of each short-circuit pin of the short-circuit wall is connected to the ground plane after passing through the substrate.

Description

technical field [0001] The invention relates to the field of wireless energy transmission, and more specifically relates to a wide-beam dual-polarization microstrip antenna based on a short-circuit wall structure. Background technique [0002] Wireless power transfer technology (MPT) refers to a process in which energy is transmitted from an energy source to an electrical load through wireless transmission. It converts electrical energy into microwaves, and allows the microwaves to be transmitted to the target position in free space, and then rectified and converted into DC electrical energy. , providing DC power supply. MPT can realize long-distance energy transmission, and has always been a research point that has attracted much attention. [0003] The MPT transceiver antenna is at the front end of the system, responsible for receiving or transmitting energy from free space, and is one of the most important components of the MPT system. In order to meet the performance r...
