| Abstract: | This paper presents a highly efficient and high‐gain single‐port dual‐band antenna designed for WLAN applications. The antenna offers −10 dB impedance bandwidths of 450 MHz (2.3–2.75 GHz) and 2300 MHz (3.95–6.25 GHz), covering the WLAN 2.4 and 5 GHz bands. It consists of a radiating patch and an artificial magnetic conductor (AMC) reflector with overall dimensions of 50 × 80 × 28.2 mm. Both the radiating element and the AMC unit are attached to an FR‐4 substrate with a relative dielectric constant εr of 4.4 and loss tangent tanδ of 0.02. By incorporating the reflector, the antenna achieves directional radiation and high gain. The proposed antenna prototype was tested, demonstrating total efficiencies exceeding 83% in both frequency bands. Additionally, at the operating frequency of 2.4 GHz, the simulated and measured half‐power beamwidths are approximately 100° and 86°, respectively. At the frequency point of 5.5 GHz, the simulated and measured half‐power beamwidths are approximately 56° and 50°, respectively. [ABSTRACT FROM AUTHOR] |
