A wideband microstrip‐fed monopole antenna with two shorted inverted‐L coupled lines is presented. The proposed antenna has a large impedance bandwidth covering the range from 3.22 to 11.68 GHz. The radiating elements only occupy a small area of 9.3 × 8.2 mm 2 . The gain and bandwidth of the antenna are predicted using a commercial finite‐element method software package. For frequencies across the operating bands, the proposed antenna displays monopolelike radiation patterns and good antenna gain, given its small physical size. The predicted results show good agreement with measured data. © 2006 Wiley Periodicals, Inc.
