Wire antenna for dual wideband cellular phone application

A high performance wire monopole antenna fabricated using two folded and meander wires as radiator is presented. A prototype of the proposed monopole antenna with a compact area size of 46 mm × 10 mm × 9 mm is implemented, and the antenna shows a wide operating bandwidth of about 273 MHz and 557 MHz for low band and high band bandwidth, making it easy to cover the GSM, EDGE, CDMA, CDMA 2000, W-CDMA and UMTS band for wireless communication and 2.5G/3G dual mode operation of a mobile handset phone. In this thesis, the study mainly focuses on the current trends in development of compact and low profile multi-media PDA and Smart mobile phone and provides a wideband 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.
