Abstract

This paper presents a study of a novel optically transparent planar antenna operating at a resonant frequency of 8.5 GHz, specifically designed for WiMAX wireless communication systems. The antenna is fed by a 50 Ω microstrip line and exhibits a wide operational bandwidth. Measuring 30 × 30 mm² and achieving an optical transparency exceeding 70% of glass, the proposed antenna delivers outstanding performance while minimizing its visual impact. It is fabricated using an innovative rectangular meshed pure copper grid layer, deposited on a 0.7-mm-thick borosilicate flat glass substrate, optimizing both transparency and conductivity. Experimental evaluations of key performance parameters, including the reflection coefficient, radiation pattern, and gain, were conducted to assess the antenna's effectiveness at the target frequency of 8.5 GHz. The measured results confirm that the antenna exhibits excellent impedance matching at 8.5 GHz, achieving a peak realized gain of 5.2 dBi. These findings demonstrate the feasibility of transparent antennas that offer performance on par with non-transparent alternatives, while providing distinct aesthetic advantages. As a result, the proposed antenna presents a viable solution for applications requiring both functionality and visual integration, such as smart devices and architectural installations.
