A compact single-layer tri-band directional antenna for Wi-Fi 6/6E applications
A compact single-layer, single-feed tri-band directional antenna is presented for Wi-Fi 6/6E systems. The target bands at 2.4, 5.2, and 6.0 GHz yield a highest-to-lowest frequency ratio of 2.50, making compact integration of the low-band radiator particularly challenging. To address this issue, the 2.4-GHz driven patch...
