Summary:
Nowadays smart mobile handsets proving various services come into the spotlight. Thus, development of a small, light and thin antenna becomes more important. In addition, antennas have been required to cover multiple bands. In modern mobile handsets, planar inverted-F antennas (PIFA) are generally used as built-in antennas because the PIFA has a number of advantages [1]. However, conventional PIFAs have a narrow and single band impedance bandwidth. In order to overcome these defects, numerous studies related to PIFAs for multiple bands operation have been devised. These studies generally focused on designing shape of the upper patch [2]-[3] and adjusting the location of the feeding line and shorting pin [4]. In this paper, a novel PIFA having multiple bands, which simultaneously resonates in different bands when excited by the same voltage feeding source, is proposed. The PIFA operates at 1.75GHz band while the slot antenna on the ground plane operates at 2.4GHz. The proposed antenna is designed to operate at Digital Communication System (DCS1800, 1710?1880 MHz), Wireless Broadband in Korea (Wibro in Korea, 2300?2390 MHz), Bluetooth (2400?2480 MHz), and Satellite Digital Multimedia Broadcasting (S-DMB, 2630?2655 MHz) frequency bands. The simulations are carried out by a finite-element-method (FEM)-based commercial software, Ansoft HFSS.
