Abstract :
This paper presents a band-suppressed PIFA antenna for UWB application using spiral slot. The modeling of the antenna geometry structures and the optimisation of the full antenna assembly was carried out in the frequency and time domains using Ansoft HFSS and CST respectively for comparison. The impedance bandwidth for reflection coefficient |S11| less than -10 dB covers the range from 3 GHz to 12 GHz, with band rejection from 4.75 GHz to 5.75 GHz. The simulated antenna gains and radiation patterns are given also, to fully describe the antenna performance.
