Abstract
This paper presents a new simple feeding technique suitable for suspended MSAs (microstrip antenna) with ultrawideband (UWB) performance. Antennas with the feed network presented here offer an impedance bandwidth (S11 < -10 dB) in excess of 50%. The antenna geometries demonstrated here are fed through a sub-miniature (SMA) connector, which is located aside the rectangular radiating element. The coaxial probe located off the radiating element supplies the energy to the main antenna element through a capacitive means. Of the two configurations demonstrated here to offer the return loss bandwidth of 52.83% (antenna 1) and 56.14% (antenna 2), respectively. The corresponding values of the measured results are 52.30% and 56.12%, respectively. Further, both cases presented here offer a gain of more than 5 dB and good radiation characteristics over the whole frequency band of interest. The antenna geometries presented here have been optimized with detailed parametric studies. Further, the experimental results presented here exhibit a good match with the simulated data.

Keywords
