CPW-coupled-fed elliptical monopole UWB antenna with dual-band notched characteristic

摘要

This paper presents the results of a coplanar-waveguide (CPW)-coupled-fed elliptical monopole UWB antenna (CCFEMUA) with a dual band-notched characteristic. The antenna has a large bandwidth covering the frequency band from 2.4 GHz to 152 GHz with the return loss larger than 10 dB. Two band notches at 3.7GHZ and 4.8 GHz are realized by cutting two half-elliptical-arc slots on the radiation patch The return loss, radiation pattern, peak gain and efficiency of the antenna are studied using computer simulation.
