Ultra-wideband monopole antenna with expanded horizontal plane open circuit section and semi-oval slot

Abstract

The invention discloses an ultra-wideband monopole antenna with an expanded horizontal plane open circuit section and a semi-oval slot. The front surface of a microwave substrate is a metal surface and adopts a coplanar waveguide feed form; one section (which stretches out and is higher than metal grounds at two edges) of a feed line is a metal coupling wire; the metal coupling wire is connected with the bottom surface of a rectangular metal sheet with an upward opening and the semi-oval slot; and meanwhile, the metal grounds at the two edges are upwards extended, namely, one section of expanded horizontal plane open circuit section respectively extends at each one of two outer sides of the metal grounds. The antenna sufficiently utilizes a feed manner of coplanar waveguide and realizes the ultra-wideband performance through a rectangular patch with the expanded horizontal plane open circuit section and the semi-oval slot; the radiation property of a monopole is met; and meanwhile, the antenna is relatively compact and characteristics of single surface can be relatively and conveniently integrated with other circuits. The antenna is simple to manufacture and is easily integrated with a PCB (Printed Circuit Board); and the ultra-wideband monopole antenna can be widely applied to various ultra-wideband wireless communication systems of hand-holding, data transmitting, imaging, target identifying and the like.

Description

technical field [0001] The invention relates to an ultra-wideband monopole antenna, in particular to an ultra-wideband monopole antenna with extended ground plane open joints and semi-elliptical slots. Background technique [0002] With the rapid development of high-speed integrated circuits, system equipment is constantly moving towards the direction of multi-functional integration, small integration, modularization, and intelligence. As the terminal equipment of the radio system, modern electronic equipment puts forward higher performance requirements for the antenna: broadband, miniaturization, small size, light weight, easy to manufacture, low cost, easy to integrate, etc. [0003] Due to target recognition, imaging, anti-stealth and anti-jamming, as well as higher and higher requirements for transmission information content, the frequency band and bandwidth of modern radar and communication equipment are constantly expanding. The technical characteristics of ultra-wide...
