Introduction With the rapid development of the mobile communications and the telecommunications industry, the cellular phone has become a popular consumer devices. The phone with small size, multi-function and high-performances is the trend, and this put forward the antenna design for cellular handsets to meet higher requirements [1]. As a result, the need for wireless communication handsets antenna with at least five multiple resonances covering different bands has grown substantially [2]. Furthermore, by comparing to the conventional external monopole or helix antennas, a mobile phone antenna that can be integrated into the handset offers many advantages, such as less easily broken off, reduced power absorption by the head, and less sensitive to the geometry of the handset [3]. The planar inverted-F antenna (PIFA) is widely used in mobile device because it can offer compact size and multiband internal antenna operation. In most of the research on multiband PIFA technology, the major success achieved has been in the design of a single feed PIFA with dual resonant frequencies. Depending upon the wide bandwidth around the resonant frequencies, the dual resonant PIFA can potentially cover more than two bands [4, 5]. In this paper, we propose a PIFA for multiband operation covering K-PCS (Korea-Personal Communication Service, 1750 – 1870 MHz), US-PCS (US-Personal Communication Service, 1850 – 1990 MHz), WCDMA (Wideband Code Division Multiple Access, 1920 – 2170 MHz), Wibro (2300 – 2390 MHz) and Bluetooth (2400 – 2485 MHz) bands. The proposed antenna is consisting of three parts with rectangular slot and parasitic element. 2.
