    A V-band, switched-beam, linearly-polarized transmit-array antenna enabling self-pointing point-to-point communication systems, e.g. wireless backhaul applications in future mobile networks is presented. The antenna is designed and fabricated using standard PCB materials and processes as well as commercially available switches. The design and characterization of the unit-cells and the transmit-array panel are presented and demonstrate state-of-the-art performances with an experimental realized gain of 33.4 dBi, an aperture efficiency of 48% and a 3-dB bandwidth of 15.4%. Furthermore, the transmit-array fed by the focal array is presented and demonstrates radiation properties and beam-switching capabilities with five beams at 0°, ±2.4° and ±4.8°, and a 3-dB angular coverage of 13.2°.
