Abstract

In this article, an UWB (Ultra-wide Band) compact monopole antenna with triple band-notched characteristics is presented. The proposed structure is designed on the FR-4 substrate with εr=4.3, tan δ = 0.025. The antenna structure consists of half-hexagon monopole with rectangular and square resonant spirals structures for the exclusion of frequency bands for WiMAX (3.25-3.85GHz), WLAN(5.15-5.85GHz) and Fixed/Mobile Satellite Communication (7.55-7.75GHz). The compact antenna of size 28x 29 mm2 achieves simulated ultra-wide bandwidth of 14.7GHz (2.9GHz-17.6GHz) and measured bandwidth of 14.8GHz (3.21-18.0GHz). The stable gain characteristic is obtained for pass band and gain is reduced to -2.02dBi (3.57GHz), 0.4 dBi (5.3GHz) and-2.75dBi (7.6GHz) at band notch frequencies.
