Abstract
In microwave and millimeter wave applications, slot antennas fed by coplanar waveguides (CPW) are receiving increasing attention. These antennas have several useful properties, such as wider bandwidth as compared to microstrip patch antennas and easier integration of solid-state active devices. In this paper novel CPW-fed wideband slot antennas are presented. The design procedure of CPW-fed Hybrid Slot Antennas (HSA) having impedance bandwidths up to 57% are described. Theoretical and measured results are shown. We also describe the design procedure of CPW-fed log-periodic slot antenna (LPSA). The impedance matching and the radiation characteristics of these structures were studied using method of moment technique. Simulated and measured results for different dielectrics are presented.Citation
