Antenna arrays for unmanned aerial vehicle

This paper presents two antenna solutions for an Unmanned Aerial Vehicle (UAV), where the available space for the antenna in the UAV has a cylindrical form. The antennas will operate at 2.45GHz in the Wi-Fi frequency band. The designed antennas are composed by a circular array of four elements conformed to cylindrical shape. A rectangular microstrip patch antenna and a PIFA antenna have been selected as basic the radiating elements of each array. Simulation results show a good matching level at the operating frequency and radiation patterns with a quite omnidirectional behavior for both antenna arrays.
