Design simulation and analysis of dual band patch antennas: Mobile communications handsets with internal antennas become more popular every day. These integrated antennas must be designed to fit into a small volume, with an arbitrary shape.Indeed, the design of modern handsets is mostly fashion- oriented, and the antennas must be adapted to these requisites, without detriment to their matching or radiating performance. The present study focuses on how a change in some of the antenna geometric parameters, such as its height, may affect itsactual performance.Dualband antennas are useful in...
