Abstract
This chapter describes a comparison study between the techniques of coplanar waveguide (CPW) and microstrip line applied to antenna in the ultra-wide band by analyzing the different parameters achieved into simulation and fabrication. Fractal geometry has been chosen to design the radiating patch of both types of antennas by including two electromagnetic solvers based on two different numerical methods: CST of microwave studio and ADS. The parameters S11, current density, gain, and the radiation pattern have been achieved into simulation and measurement in the frequency range 3.1 – 10.6GHz released by the Federal Communications Commission (FCC) as a commercial UWB. The photolithographic technique, the network analyzer, and the anechoic chamber have been involved to perform the fabrication and the measurement of the validated microstrip and CPW antennas.
