Design of microstrip ultra wide band antenna with two notch filters for wireless communication by Abdulhasan, Raed Abdulkareem

“…In order to add reconfigurable characteristics to the patch antenna, two copper strips are putted on the slots to represent the ON and OFF switching status of an ideal Pin diode. By using this simple switching technique, the current distribution of the patch changes and enables the antenna to have four modes of operation. …”
