| Abstract | Switched-beam transmitarray antennas operating at E band (71-76 GHz and 81-86 GHz) are investigated in the perspective of self-alignment applications for point-to-point wireless communication links, which play an increasing role in modern mobile networks infrastructures. Several designs are presented covering either one or both sub-bands. Simulation results exhibit promising performance with gain levels in the range of 31-35.1 dBi for a 100-mm diameter aperture. The design of a switched focal array is presented and enables the coverage of an angular sector of ±6.6° with 5.1 dB gain variation in the lower band and ±6.9° with 6.8 dB gain variation in the upper band. © 2017 Euraap. |
