Summary:
Currently, development of wireless communications is rapidly expanding, which leads to the requirement of using a single antenna to cover multiple applications for mobile devices. For these applications, triple or multiband planar monopole antennas are very suitable since they are compact, low profile and easy to fabricate. Recently, many multiband antenna researches have been widely investigated for wireless applications at this aim [1-2] .In addition, a dual-band operation for the application in the wireless local area network (WLAN) communication systems has been successfully designed [3-5]. The antenna properly incorporated with open-end slits on the ground plane has demonstrated for antenna performance improvement [6]. However, a multiband system is becoming necessary to provide more services including Universal Mobile Telecommunications System (UMTS) and personal communications system (PCS), wireless local area network (WLAN) 5.2GHz. In this paper, we propose a planar monopole antenna with fixed slot cuts in the ground plane. The proposed antenna is not only compact in size but also capable for multiband operation such as PCS (1850?1990 MHz), UMTS (1920?2170 MHz), and WLAN (5150?5350 MHz). In addition, the proposed multiband antenna with relatively low profile is very suitable for multiband mobile communication systems. The experimental results and the details of the proposed antenna design are both presented and discussed.
