Problems solved by technology

[0003] With the increase of antenna density, antennas can be seen everywhere. Although it brings a lot of convenience to people, it also makes many people worry about the harm of electromagnetic waves to the human body. Some people feel uncomfortable because of the mental pressure caused by this worry. The more serious ones even suffer from "electromagnetic anxiety disorder", which affects personal health and life, and also destroys the aesthetics of the building environment

Abstract

The invention relates to the technical field of antennas, and relates to a circularly polarized patch antenna shaped like a Chinese character 'jia'. The antenna includes a ground plate and a dielectric layer plate, wherein the ground plate and the dielectric layer plate are parallel to each other. The dielectric layer plate is arranged above the ground plate. A metal sheet A is arranged at the top of the dielectric layer plate, and a metal sheet B is arranged at the bottom. A 3D L-shaped probe is arranged between the ground plate and the dielectric layer plate. The 3D L-shaped probe consistsof a vertical rod and two horizontal rods of equal length. One end part of one horizontal rod and one end part of the other horizontal rod are fixedly vertically connected. The top of the vertical rodis fixedly connected with the common end part of two horizontal rods. Each horizontal rod is parallel to the dielectric layer plate. The vertical rod is perpendicular to the ground plate. The groundplate is provided with a through hole. The lower end of the vertical rod passes through the through hole and is connected with the coaxial connector arranged at the bottom of the ground plate. The ground plate and the dielectric layer plate are square, and the length of the sides is the same. The metal sheet A is shaped like a Chinese character 'jia'. The antenna provided by the invention has theadvantages of simple structure, low cost, beautiful appearance, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a "jia"-shaped circularly polarized patch antenna. Background technique [0002] Circularly polarized patch antenna refers to the direction and size of the magnetic field intensity vector in the broadside electromagnetic field radiated by the planar antenna is not fixed in space, but changes with time and forms an approximate circle in a certain plane track. [0003] With the increase of antenna density, antennas can be seen everywhere. Although it brings a lot of convenience to people, it also makes many people worry about the harm of electromagnetic waves to the human body. Some people feel uncomfortable because of the mental pressure caused by this worry. The more serious ones even suffer from "electromagnetic anxiety disorder", which affects personal health and life, and also destroys the aesthetics of the building environment.
