Abstract
this paper, an ultra wideband circular printed monopole antenna is presented. The antenna performance will be studied using the two readymade software package IE3D and CST. The regular monopole antenna will be tuning by adding two C-shaped conductor near the antenna feeder to control the rejection band inside the WLAN frequency range (5.15-5.825GHz). The simulation results using the two software packages will be compared to each other. An empirical formula for the variation of the rejection band frequency against the mean length of Cshaped conductors is derived. The effect of the variation of the C-shaped conductor mean lengths on the center frequency of the rejection band will be discussed. The WLAN band rejection will be controlled by using two groups of PIN diodes. The circuit will designed on RT/Duriod substrate (εr=2.2, h=1.57 mm, tanδ = 0.00019), where the simulations results using IE3D and CST are in good agreement with measurement results.
