In this chapter, a novel low-profile wideband 1Õ2 array microstrip patch antenna has been proposed for wireless local area network (WLAN) applications. The antenna is comprised of a microstrip feed line and a directly coupled T-shaped junction, which is connected to circular patches through sub-feeders. The material of the substrate is Rogers RT5880. The ground plane is nearly half the size of the antenna. The antenna has an overall dimension of 40 Õ 22.4 Õ 0.79mm3. The antenna is developed step-by-step to evaluate gain and radiation pattern characteristics for optimum performance. The antenna is designed, simulated, and analyzed using CST Microwave Studio. The simulated outcomes are consistent. This antenna is suitable for IEEE 802.11a/h/j/n/ac/ax WLAN applications due to its operating 106frequency range of 4.72–6.32 GHz and center frequency of 5.672 GHz. Therefore, the simulated verification indicates the proposed antenna could be a suitable choice for WLAN applications.
