Coplanar Waveguide Fed Ultra Wide Band Monopole Antenna

In this paper, we present a novel coplanar waveguide (CPW) fed printed monopole antenna for ultra wideband communications. The antenna was fabricated on a 0.762 mm thick GML (relative permittivity of 3.2) substrate. The antenna structure was analyzed using a transmission line matrix (TLM) method based flomerics micro-stripes (version 7). The measured 10 dB return loss impedance bandwidth of the fabricated antenna is approximately 116%. The fabricated antenna exhibited omnidirectional radiation pattern and the measured results show a good agreement with the simulated one. Detailed characteristics of the antenna as a function of changes in various structural parameters are also reported
