Summary:
Modern portable communication systems have experienced very high growth in recent years and the trend is likely to continue. With this rapid development, a single handset must support many services including voice data, video, broadcasting, and digital multimedia contents. These service necessities for the handsets lead to a great demand to develop a small antenna with multi-bands capability in the transceiver. Now, the requirement for quad-bands, five-bands or six-bands antenna is urgent for mobile communication. In additions, low cost, compact size, easy fabrication, and wideband are also important issue for handset antenna design. The planar inverted-F antenna, which is easily embedded in a handset, is a good candidate to meet above-mentioned requirements [1-2]. Many new designs of the multiband antenna based on PIFA concept for achieving operation at traditional quad-band, i.e., GSM900, DCS1800, and PCS1900 and IMTS2000, have been reported in the open literature [3]. Furthermore, some published papers extended the multi-band function to include more bands, such as GPS1700, ISM2450 or WiMAX (2.305-2.69GHz) [4-5]. Various internal antennas which applied many size reduction techniques or bandwidth enhancement approach have been proposed recently. In this paper, a six-bands compact PIFA design that still owns compact size will be presented to cover the operating band of WiMAX (3.5GHz) and WLAN within the 5-6GHz for the applications of the IEEE802.11a and HIPERLAN. The proposed antenna consist a main patch with two slit-cuts and two parasitic elements. The geometry size of the proposed is shrunken to meet the requirements for a practical handheld. The antenna size was realized within a volume of 40*25*8 mm3 . By varying the meandered slit-cuts, the desired operation at the hexaband frequency bands is able to be implemented. Designed parameters and simulation results will be discussed in this conference. Finally, the prototype antennas are constructed and measurement is performed to verify the simulation results.
