Radiation Pattern Characteristics of Multiple Band-Notched Ultra Wideband Antenna With Asymmetry Slot Reconfiguration

Radiation pattern characteristics of reconfigurable asymmetry slotted ultra wideband antenna with multiple band-notched are presented. The proposed antenna is planar monopole, consisting of a microstrip feed line and modified L and U slots with a pentagonal patch on the front side and half ground plane is on the back side of the board. The measurements were conducted by using Radio Frequency measurement and instrumentation facilities, software tools available at the Wireless Communication Center in Universiti Teknologi Malaysia. The modified antennas are designed for having reconfigurable frequency notched at Fixed Wireless Access, High Performance Local Area Network, and Wireless Local Area Network.
