一种新型平面超宽带天线的设计

doi:10.3969/j.issn.1000-0801.2011.08.018

Abstract

Abstract:

A microstrip-fed novel planar ultra-wideband monopole antenna with a metal patch of arc side and a notched ground plate is proposed.A notch of semicircle unite isosceles trapezoid structure divided the ground into two coupled parts,the antenna impedance matching and bandwidth have been enhanced.The simulation results show that return loss＜-10 dB bandwidth covers a frequency range between 3 GHz and 11.8 GHz.And the frequency range that VSWR＜1.5 is between 3.4 GHz and 11.2 GHz,with good omni-directional radiation performance.This type of antenna is simple in structure,small in size,suitable for UWB communications.

Key words: microstrip-fed, planar ultra-wideband monopole antenna, isosceles trapezoid, arc, notch
