Abstract :
In this paper, we present a novel coplanar waveguide (CPW) fed printed pentagonal monopole antenna for ultra wideband communications. The antenna is fabricated on a 1.59 mm thick FR-4 (relative permittivity of 4.4) substrate. The antenna structure is analyzed using a transmission line matrix (TLM) method based Flomerics Micro-Stripes (version 7.5). The measured 10 dB return loss impedance bandwidth of the fabricated antenna is approximately 8.16:1. The fabricated antenna exhibits omni-directional radiation pattern and the measured results show a good agreement with the simulated one. It has been demonstrated numerically and experimentally that this antenna is suitable for ultra-wideband (UWB)/ IEEE 802.16a applications.
