The rapidly growing communication market demands for powerful and low cost antenna systems operating at micro/mm-wave frequencies. Tunable phase shifters are the key components of steerable antennas. The system costs would be significantly lowered by using optical control techniques. Moreover, optical switches can offer the advantages of continuous, quick and low power consumption and are free from EMC issues. Here we describe and show measured data of a novel steerable antenna array incorporating optically controlled EBG phase shifters.
