Abstract

In this letter, the design, the analysis, and the measurement results of a new compact planar ultra‐wideband CPW‐fed antenna with dual‐notched characteristics are presented. The radiating element is a planar square monopole with a circular base. A dual‐notched bands characteristic is obtained by etching a half‐circle slot in the square monopole and two L‐shaped slots in the ground plane. The measurement results show stable radiation patterns with broadband matched impedance from 3 GHz to 11 GHz for VSWR < 2, except two dual‐notched bands at 3.3–4 GHz and 5.2–5.8 GHz for filtering the WiMAX and WLAN signals. © 2010 Wiley Periodicals, Inc.
