Abstract :
Modern mobile handset devices are required to operate at multiple frequency bands so as to provide various services [1,2]. As is well known, for the future mobile communication systems (the emerging third generation or beyond), the frequency band around 2 GHz is very wide (GSM1850, GSM1900, DCS, PCS, UMTS, WiBro), in addition to existing GSM bands around 900 MHz. Additionally, Bluetooth and WLAN systems at 2.45 GHz ISM band, as well as GPS at 1.57 GHz are desired to integrate into a handset device. This results in a total bandwidth requirement of 1 GHz (from 1.5 to 2.5 GHz) near 2 GHz. Operation around 5 GHz (IEEE 802.11 j/a) for WLAN applications is also required for personal communication handsets.
