Abstract
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°.
