Unmanned Aerial Vehicles (UAVs) has a lot of applications in military as well as civil sectors. UAV applications includes search and rescue traffic monitoring, mapping, remote sensing, surveillance and even wireless communications relays. Any UAV has two wireless communication links with its ground station, a control link and a data link. In this paper, a 12-element patch planar antenna array is designed, fabricated and tested along with its Radio Frequency (RF) feed network at 2.45GHz. The array is designed to be embedded in the wing structure of a fixed wing hobby-type UAV.
