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.

Epoxy Material

A spiral fork shaped hexagonal micro strip patch antenna is designed to operate at different frequencies, which are in ultra-wide band range (3.1-10.6GHz). The newly presented antenna is simulated on a Flame Retardant - 4 (FR4) epoxy material with dielectric constant 4.4and overall size of structure is 28*28mm2 . Coplanar waveguide feeding (CPW) is used in this design for easy simulation. This proposed triband structure resonates at 1.36GHz, 5.74GHz and 8.8GHz. The proposed pentaband antenna resonates at 2.38GHz, 3.64GHz, 6.76GHz, 7.36GHz and 8.98GHz with corresponding impedance bandwidths are 200MHz, 70MHz, 170MHz, 520MHz and 420MHz. The peak gains at their resonant frequencies are 1.77dB, 2.45dB, 3.53dB, 4.54dB and 2.28dB respectively with good radiation characteristics. These antennas are suitable for S - , C - and X - band applications.
