چکیده

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

A U-Shaped Slot UWB Antenna with Flexible and Wide Tunable Dual Notch Band

A coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with flexible and wide tunable dual bandnotched characteristics is proposed in this paper. The dual band-notched function is achieved by using an U-shaped slot inserted into the ellipse radiation patch and by using an elliptic parasitic slit placed near the ground plane. The wide tunable band-notched characteristic is implemented by ad...
