A high performance dual band monopole antenna fabricated using single folded wires as radiator is presented. A prototype of the proposed monopole antenna with a compact area size of 6mm?6mm?10mm is implemented, and the antenna shows a wide operating dual bandwidth (referenced VSWR=3) of about 295MHz and 343MHz for low band and high band bandwidth, making it easy to cover the GPS and Wi-Fi band for wireless communication and consumer electronics operation of a mobile handset PDA. In this paper, the study mainly focuses on the current trends in development of compact and low profile GPS antenna and Bluetooth/Wi-Fi co-existence antenna built in PDA and Smart mobile phone and provides a dual band monopole antenna design suitable for application in wireless communicating system in the near future.
