A novel CPW‐fed compact inverted L‐strip ultra wideband (UWB) microstrip antenna is proposed for ultra wide band applications. The proposed antenna possesses a method to minimize the monopole antenna by loading of inverted L‐strip over the conventional monopole patch antenna to lower the height of the antenna. The ground was vertically extended toward two sides of the single radiator. Therefore, the large space around the radiator that is usually wasted can be effectively saved. The antenna is practically fabricated and simulated. Measured results show a good agreement with simulated results. The prototype with overall size of 25 × 25× 1.6 mm 3 achieves good impedance matching, constant gain, stable radiation patterns, and constant group delay over an operating bandwidth of 2.6–13.04 GHz (10.44 GHz). © 2013 Wiley Periodicals, Inc.
