A novel wire antenna for GPS and WLAN co-design

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. By utilizing the monopole antenna structure, the proposed antenna design is easy to be embedded into the mobile phone application.
