Introduction The wireless revolution has spawned a flood of new products that dramatically increase the availability of voice and data nearly anywhere in the world. While this revolution has significantly expanded the opportunity for new and better wireless communication terminals, it has made design considerations for antennas more involved than ever before. Before the evolution of mobile handsets and portable wireless terminals, antenna engineers were able to develop designs based on individual radio specifications and requirements. Elements of the design included a variety of factors, such as gain, bandwidth, and polarization. However, with the recent emphasis on reducing size, providi
