Abstract
A novel compact 5.2 GHz notched ultra‐wideband (UWB) CPW‐fed monopole antenna using dual reverse split trapezoid slots which has small area of (16 × 17 mm^2^) is proposed. The designed antenna operates over 3–11 GHz for VSWR ≤ 2 including the WLAN band notched at the vicinity of 5.2 GHz. The dual reverse split trapezoid slots are employed effectively for notching unwanted frequency band such as that for WLAN service, since it can be implemented with a small dimension and in a high Q operation similarly to the conventional strip‐type dual reverse split ring resonator (SRR). Based on the simulated and measured results, a band notched UWB antenna using dual reverse split trapezoid slots is very effective in rejecting unwanted frequency in terms of its selectivity. Good monopole‐like radiation patterns and antenna gains have also been obtained. © 2008 Wiley Periodicals, Inc.
