Abstract :
In this paper, a dual-band coplanar ring and patch antenna 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 Omega 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. It has a gain of about 5 dBi for both frequencies
