A novel electromagnetically coupled circular patch antenna (CPA) with an eroded ground plane is proposed for the wireless local area network (WLAN) application. First, a simple CPA is designed for 2.4‐GHz WLAN band. At this frequency, the physical size of the CPA is large. Therefore, a CPA is designed at a higher frequency with much lesser dimensions, and some portion of the ground plane is eroded to observe the percentage of resonant frequency reduction. In order to avail the WLAN services at 2.4 GHz, a CPA is optimally designed at 5.76 GHz based on the same proportionality technique with an eroded ground plane. This miniaturized antenna resonates at 2.4 GHz frequency with excellent reflection and radiation characteristics. The simulation software ANSYS high‐frequency structure simulator is considered for the design of the proposed CPA. The CPA is physically fabricated and its characteristics are validated with the simulation result. It is also compared with some of the antennas available in the literature for the WLAN application. The comparative study shows that the proposed CPA is a miniaturized one with attractive performance parameters.
