Abstract

This paper presents a dual-band patch antenna operating at 5.2 and 6.6 GHz for WiFi 6/6E communication systems. Unlike conventional approaches based on higher-order modes or stacked structures, which often lead to larger size and complicated structure, the proposed design employs two closely spaced patches of different sizes printed on the same layer to realize dual-band operation. These patches are capacitively excited through a centrally located probe-fed microstrip line, enabling a single-layer, low-profile, and low-complexity configuration. The optimized antenna occupies an overall size of 0.52 λ × 0.52 λ × 0.03 λ at the lowest operating frequency of 5.2 GHz. The measured impedance bandwidths are 6.1% (5.12–5.44 GHz) and 4.9% (6.40–6.72 GHz) for the lower and upper bands, respectively. Within these bands, the antenna achieves maximum broadside gains of 7.0 and 6.7 dBi, while maintaining stable and desirable radiation characteristics across both operating frequencies.
