Grid-oscillator beam-steering array
Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting
Preserved Fulltext
Recently Liao and York showed that beam-steering can be achieved by detuning the end elements of a coupled-oscillator array. The advantage of this approach is that no phase shifiers are required. Liao and York used a single line array of patch antennas. Here we report the results for a pair of 1 x 4 HEMT line-grid oscillators at 11 GHz. This array can scan from -6.5' to +5' by changing the bias.
