Earth plate slot radiation n-type parasitic structure multi-frequency planar monopole antenna

Abstract

The invention discloses an earth plate slot radiation n-type parasitic structure multi-frequency planar monopole antenna, comprising: a square dielectric substrate; a monopole rectangular radiation arm disposed on the upper surface of the square dielectric substrate; an n-type metal parasitic structure disposed on the upper surface of the square dielectric substrate; and a metal earth plate disposed on the lower surface of the square dielectric substrate. The monopole rectangular radiation arm is a rectangular metal patch. The axis of the monopole rectangular radiation arm in parallel to a long arm passes through the center of the upper surface of the square dielectric substrate. A short side of the monopole rectangular radiation arm coincides with a first side of the upper surface of thesquare dielectric substrate, and the centers of two edges coincide with each other to serve as a feed port of the earth plate slot radiation n-type parasitic structure multi-frequency planar monopoleantenna. Two groups of rectangular slot structures are etched symmetrically on the metal earth plate. The earth plate slot radiation n-type parasitic structure multi-frequency planar monopole antennasolves the technical problems that the antenna of an existing wireless mobile communication system has a single operating frequency and thus leads to an increase in system complexity and a decrease inreliability.

Description

technical field [0001] The invention belongs to the field of wireless mobile communication system terminal equipment, and particularly relates to a planar structure antenna. Background technique [0002] The rapid development of information technology not only brings great convenience to human life, but also changes the traditional production and lifestyle. Especially after the arrival of the fifth-generation wireless communication technology characterized by high speed, low latency and large capacity, all things in the whole society can be connected to the Internet, and can be intelligent or remotely controlled. Since then, human society has entered the era of intelligence and wisdom. But all these beautiful lives come from wireless communication technology. The antenna is the basic element of the wireless communication system, which converts the high-frequency current in the wire into the electromagnetic wave propagated in space or vice versa, converts the electromagneti...
