Abstract

In this chapter, a novel dual-band balanced antenna fed coplanar waveguide approach for use in WLAN standards is investigated, studied and prototyped. Within this design process, the need of the balanced feed network was eliminated. This is realized by carefully and systematically calculating and studying the influences of the key antenna modified parameters. This effective analysis was done with the aid of two EM simulator tools in order to ensure accuracy and verification of the consequences. Finally, the optimum antenna model was prototyped and verified, in which its results in terms of return loss, power gains, far-field and efficiency were compared with simulated ones.
