Abstract. Antennas exhibiting a directional radiation pattern are needed for point-to-point links and can be used to extend the coverage of a wireless network. Printed directional antennas offer the additional benefits of being compact and readily integrable with circuit boards. The talk will review the design and experimental testing of a few planar directive antennas working in the 2.44 GHz band. In particular, the classic Yagi-Uda array, composed of one driven element and many parasitic radiators, can be adapted to a planar FR4 board; by shaping the ground plane and by carefully adjusting the dimensions of the parasitic radiators it is possible to achieve a satisfactory input impedance matching and to avoid the presence of an external balun. Moreover, these printed parasitic arrays give some freedom in the choice of the radiation pattern main lobe direction.
