Abstract
A novel monopole antenna, constructed easily by folding a simple metal plate, is presented. The folded metal‐plate monopole antenna shows a compact size of 10 × 10 × 70 mm^3^ and has three wide impedance bandwidths at about 0.9, 2.0, and 5.0 GHz, thus covering the operating bandwidths of most of the present‐day mobile communication systems (AMPS, GSM, DCS, PCS, and UMTS) and the WLAN systems in the 2.4/5.2/5.8‐GHz bands. With the antenna performance obtained, the proposed antenna is suitable for application in a PDA phone for both mobile communications and WLAN applications. © 2003 Wiley Periodicals, Inc.
