Modeling of Ultra-wideband Coplanar Patch Antennas

This paper deals with modeling of the ultra-wideband planar antennas with coplanar feeding in the commercial available programs. After a brief summary of the basic principles of high-frequency structures modeling, a specific design of wideband antennas on two different substrates is shown. The antennas are modeled in CST Microwave Studio and Zeland IE3D. Simulation results are compared to measured data.
