 This paper proposes a compact planer Wi-Fi antenna with optimized radiation patterns for small unmanned aerial vehicles, UVs. The antenna is designed to be mounted on the outermost side of the non-metallic wing of small UVs. The antenna's dimensions are 16.5 mm x 30.3 mm x 1.6 mm, and its impedance bandwidths range from 2.11 GHz to 2.58 GHz and 5.06 GHz to 7.5 GHz, minus 10 dB s11. At 5.8 GHz, the antenna has stronger radiation below the UAV to reduce interference from rare use directions. The antenna's maximum radiation is below the UAV and between 14° and 29° from the horizontal plane. At 2.4 GHz, the antenna has quasi-onidirectional radiation to ensure a stable link in all directions. Additionally, the antenna has good vertically polarized radiation for long distance applications.
