A novel dual‐frequency planar inverted‐F antenna (PIFA) with a rolled radiating arm suitable for GSM (890–960 MHz) and DCS (1710–1880 MHz) dual‐band operation is proposed. The radiating arm is first printed on a thin flexible printed circuit board (FPCB) and then rolled onto the surface of a foam cylinder, which greatly reduces the dimensions of the proposed PIFA. In addition, the rolled radiating arm provides two separate resonant paths, leading to the excitation of two resonant modes for GSM and DCS operations. The proposed PIFA is suitable to be mounted on top of the system ground plane and shows a very low profile (only 8 mm), which makes it a very promising internal antenna to be built‐in within the housing of a communication device. © 2003 Wiley Periodicals, Inc.
