Abstract

A microstrip patch antenna radiating a fourth-order vortex beam relates to a microstrip patch antenna. A dielectric substrate is provided, and a radiation ring, a rectangular microstrip ring, and a gradient microstrip feeder are arranged on the upper surface of the dielectric substrate; the lower surface of the dielectric substrate is a copper conductor layer, and the copper conductor layer is a grounding plate; the radiation ring and The rectangular microstrip rings are connected, and the tapered microstrip feeder is connected with the rectangular microstrip rings. It has the advantages of simple structure, easy implementation, excellent performance, etc., has great application potential in the future wireless communication technology field, and plays a role in promoting the application of OAM technology to the wireless communication field.

Description

technical field [0001] The invention relates to a microstrip patch antenna, in particular to a microstrip patch antenna radiating a fourth-order vortex beam. Background technique [0002] In recent years, Orbital Angular Momentum (OAM) has attracted more and more attention from scholars because of its huge advantages in wireless communication and other fields. The current wireless communication field is developing rapidly, and the 5G era has arrived, requiring higher-speed, higher-bandwidth communication technologies to meet the needs of today's human beings. Orbital angular momentum is one of the ways that can be chosen by human beings. Its modes are mutually orthogonal, so it can be applied in wireless communication technologies such as multiplexing technology to improve communication rate and coding efficiency. [0003] At present, there are mainly five ways to generate vortex beams in the microwave field: 1. Generate vortex beams through antenna arrays; 2. Generate vort...
