Free registration required

Executive Summary

This paper presents the results of radiation pattern measurement of small reconfigurable slotted Ultra WideBand (UWB) antennas. The measurements were conducted by using RF measurement and instrumentation facilities, software tools available at WCC of Universiti Teknologi Malaysia. The original antenna's geometry proposed is slotted antenna with L and U slots. Then the slots modifications are applied in order to achieve band-notched characteristics. These proposed antennas are having band notched frequencies at Fixed Wireless Access (FWA), HIPERLAN and WLAN bands. The band-notched operation is achieved by incorporating some small gaps instead of PIN diodes into the slot antenna.
