A Compact Monopole Antenna for Wireless Personal Area Network

Abstract: A compact planar monopole antenna suitable for wireless personal area network (WPAN) application is proposed. By simply modifying the periphery of a rectangular patch, effective operational band 2.95 to 16.8 GHz is achieved. This band sufficiently covers the operating band, 3.1�10.6 GHz, of the new wireless personal area network (WPAN) using ultra wide band (UWB) technique. A prototype of the proposed antenna is fabricated and measured to verify the simulated performances of the proposed antenna. The antenna provides fractional bandwidth of 138%, peak antenna gain of 2.4 dBi. The proposed antenna is compact and of small size (20 X 30 X 1.6 mm3) with a 50? feed line and offers a very simple geometry, suitable for low cost fabrication using printed circuit board technology.
