A novel 60 GHz end-fire antenna for point-to-multipoint applications is presented. The prototype of this antenna is a dipole structure with a wide beamwidth. Then, the radiators are tilted with the ground is also modified to improve its directive gain while maintaining wide signal coverage. The antenna has a compact size of 10 mm × 7 mm × 0.254 mm. Measured results show that the antenna has favorable properties of 3-dB beamwidth up to 150° at 60 GHz, S11 less than -10 dB and stable gain of 5.9 to 6.8 dBi over 57 to 64 GHz, where these characteristics denote it fitting for 60 GHz wireless communication systems.
