In the last few years, there has been an increasing demand for multi-band antennas. In particular, the focus has been on embedded antenna designs. With the third generation (3G) wireless communications systems going to be introduced worldwide, the demand for a handheld transceiver to support both old and new standards via a single antenna becomes compulsory. Therefore, the most immediate task for the new antennas is to operate in both the new UMTS (3G standards) frequency bands and the already established frequency bands. However, there is also a requirement on handheld transceivers to serve cellular bands and new communication technologies (e.g. WLAN and Bluetooth).

In this thesis, a new embedded antenna that operates in (four frequency bands) three major global mobile communications frequency bands including GSM900, GSM1800, UMTS and Bluetooth frequency band has been designed. The antenna is a single feed and low profile Planar Inverted-F Antenna (PIFA). It has three narrow slots etched on the same side of the patch. Using software, FEKO, simulations has been carried out to investigate the antenna’s performance and characteristics. From the simulation results, it has been found that the antenna is able to operate at the desired resonant frequencies with the specific bandwidth.
