Abstract

Abstract: It presents the design of a lowprofile quadband PIFA antenna for mobile phones. The Antenna has multiband characteristics via the use of two slot and parasitic load. To enhance antenna radiation, three technologies were applied, such as digging out the ground under the feed, joining directly up groundfeed and the ground, and using passive π matching network. Experimental results show that the antenna has very good radiation performance in GSM900/DCS/PCS/UMTS operating bands, the efficiency of which is 38％、40％、42％ and 39％ respectively.

Key words: lowprofile; multiband antenna; PIFA; mobile Phone
