Abstract
A simple and compact wide-slot antenna and its extended band-notched design are presented.The proposed antenna is etched on a piece of FR4 printed circuit board with an overall size of 30 × 28 × 0.8 mm3. It consists of a polygonal wide slot, a coplanar waveguide feeding line, and a circular metal ring. The antenna prototype achieves good impedance matching, a constant gain, and stable radiation patterns over an operating bandwidth of 3.1–10.6 GHz. Furthermore, after the addition of an assembled band-notch structure, which is formed by a pair of inverted L-shaped slits embedded in the ground plane and a T-shaped stub inside the metal ring, the proposed antenna exhibits band-notched characteristics and achieves a much sharper notch band at 5–6 GHz. © 2012 Wiley Periodicals, Inc.
