Abstract In this paper, a coplanar ring and patch antenna for dual‐band operation is presented. The patch is placed inside a rectangular ring. A coupling strip located in between the rectangular ring and the patch is used to excite them through a 50‐Ω coaxial cable. The proposed antenna was built on a two‐layer (FR4 and air) substrate with an area of 28 mm by 28 mm designed for WLAN in 2.4‐ and 5.2‐GHz bands. The size of the conducting ground plane is 65 mm by 65 mm. It has a gain of about 5 dBi for both frequencies. © 2006 Wiley Periodicals, Inc.
