Summary:
One of the most common antenna design for mobile devices is planar inverted-F antenna (PIFA) design [1-3], which normally covers the quad-band operation such as global system for mobile communication (GSM, 890-960 MHz), digital communication system (DCS, 1710-1880 MHz), personal communication system (PCS, 1850-1990 MHz), and universal mobile telecommunication system (UMTS, 1920-2170 MHz). Although this antenna design is attractive for achieving multi-band and broadband operations; however, it requires a top radiating patch that locates above the system ground plane, with a height commonly fixed at around 6 mm, thereby potentially increasing the thickness of the mobile devices. With the rapid growth in mobile communications, it is not until recently that dual-network system applications such as the wireless local-area network (WLAN) and worldwide interoperability for microwave access (WiMAX) are also being considered to incorporate into the mobile devices [4-5]. Hence, in this paper, a hexa-band internal printed co-planar antenna is proposed due to the advantages such as low-profile and easy to fabricate at low cost. Besides the ability to cover the usual GSM/DCS/PCS/UMTS band, the proposed antenna also includes the dual-network band operating at WLAN (2400-2480 MHz) and WiMAX (2500-2690 / 3400-3600 MHz). Details of the antenna design are described, and the measured results of all fabricated prototypes are presented and discussed.
