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 present invention relates to the technical field of antennas, and relates to a "jia"-shaped circularly polarized patch antenna, which includes a ground plate and a dielectric laminate, the ground plate and the dielectric laminate are parallel to each other; a dielectric laminate is arranged above the ground plate, and the dielectric There is a metal sheet A on the top of the laminate, and a metal sheet B on the bottom; a 3D "L"-shaped probe is installed between the ground plate and the dielectric layer; the 3D "L"-shaped probe consists of a vertical rod and two The two horizontal rods are composed of horizontal rods of equal length, one end of the two horizontal rods is vertically fixedly connected to each other, and the top of the vertical rod is fixedly connected to the common end of the two horizontal rods; each horizontal rod is parallel to the medium layer, The vertical bar is perpendicular to the grounding plate; the grounding plate is provided with a through hole, and the lower end of the straight bar passes through the through hole to connect with the coaxial connector arranged at the bottom of the grounding plate; both the grounding plate and the dielectric layer are square, and the sides The lengths are the same; the metal sheet A is in the shape of "jia"; the invention has the advantages 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. Contents of the invention [0004] Accordin...
