Abstract :
In this paper a new design for a coplanar waveguide (CPW) fed slot antenna is presented. The impedance matching and the radiation characteristics of this structure were studied using method of moments technique. This antenna has an impedance bandwidth of 49% and a radiation bandwidth 42% about its 4.8 GHz center frequency, as compared to 12-20% impedance bandwidth of the standard CPW fed slot antenna. The cross-polarization in both the principle planes is at least 20 dB below co-polarization across the entire bandwidth. Simulated and measured results of the antenna are presented. This wideband antenna has significant applications in wireless technologies.
