Abstract

Developments in the field of wireless communications resulted in the creation and approval of an unlicensed use of the ISM band. The utilization of the said frequency band encountered limitations on power and antenna gain to minimize possible interference. Antenna design is an important consideration in the implementation of any wireless system such as those operating in the ISM band. A 7-element ESPAR was designed, fabricated and tested in a typical laboratory set-up using a generator and receiver assembly. Antenna characteristics such as gain, HPBW, SWR and return loss were measured. The results show that the designed antenna exhibit directivity and ample interference rejection capability.
