Design Low Sar Microstrip Antenna For Mobile And Uwb Applications

The possibility to send electromagnetic signals through the air was first discovered in the late 19th century but only during the last two decades mobile wireless communication has become accessible to the general public. Over that period of time the mobile communications industry has become economically significant especially in Finland and a vast amount of research has been conducted to further improve the quality of wireless systems. In wireless communications systems antennas hold special significance as they are the interface to the free space. Although many of the parameters describing the performance of antennas can be used universally the targets and priority of the parameters vary significantly depending on the purpose of each antenna. Antenna design often relies heavily on reported commonly known antenna models experience and analysis. The design process typically starts with a ballpark model known to produce approximately the desired performance.
