Abstract :
In this paper, we present the design of a CPW-feed printed antenna which improves the connection between the antenna and the coaxial cable. The proposed antenna is designed to cover two frequency bands of 1.84-2.5 GHz and 4.9-6.3 GHz, which are required by the dual-band WLAN communication. In this work, it is found that the distance between the radiator and the ground is the key parameter for the design of the antenna to work in two resonant bands. Furthermore, tuning the shape of the radiator and the position of the slots on the ground will widen the high resonant band of the antenna. This design of the antenna is simulated on an FR4 substrate with a thickness of 0.4 mm and an area of 11×67 mm2. Being small in size, cheap in manufacturing, and simple in profile, the proposed antenna is perfect to be embedded into an access point of dual-band WLAN.
