Abstract
Wireless technology lately became subjected to the rapid enormous changes in frequency allocation, policies and procedures of operations, and techniques in order to enhance the performance of the wireless system as whole. A lot of wired applications are converted into wireless, for example wired LAN is turned into a wireless, which due to the huge sophisticated researches. Currently due to the advanced of the integrated technology, engineers are able to fit many diversified applications working at different frequencies in one wireless device. Consequently an increased demand for multiple antennas covering different wireless communication bands on the same platform increased extremely.
