This paper proposes a dual-band patch antenna design for the applications of wireless local area network (WLAN) and dedicated short-range communications (DSRC). To minimize the antenna size, a shorting plate as well as a shorting pin is used inside the antenna structure. In addition, slots are cut on the patch surface to create dual band operations. In order to accelerate the antenna design procedure and to optimize the antenna performance, we used a program based on an implemantation of a genetic algorithm in conjunction with the IE3D simulation software to auto-adjust the geometric parameters of the patch. The program examines the fitness of the design via the antenna's input impedance and bandwidth of operations, and utilizes a natural selection method to generate new values of the parameters. Simulated and measurement results shows distinguished antenna performances while retaining relatively small antenna profile.
