Abstract

In the last few years, there has been an increasing demand for designing multiband antennas for cellular communication devices. In particular, the focus has been on internal antenna designs. With the third generation (3G) wireless communication systems introduced world-wide, the demand to support both ald and new standards using a single method phone becomes compulsory. Therefore, the most immediate task for the new antenna is to operate at both new UMTS frequency bands and already established 2G frequency bands. In addition, there is also a requirement on mobile phones to serve some new wireless communication applications, including WLANs and buetooth. In this paper, a new compact microstrip patch antenna designed to operate at three main communications frequency bands (GSM, UMTS and Bluetooth) with single feed are presented. The antenna is designed on thick air subsrate. The antenna is mounted on top of finite ground plane that can be considered as a circuit board of practical mobile phones. The antennaare simulated and optimised for best operation using FEMLAB designer and their performance are measured and compared. A comparison between measurement and simulation is presented and show a good agreement.
