Abstract :
A novel high gain, low profile active phased array is being developed with electronic beam steering capability in the azimuth plane. The radiating elements consist of multi-segment dielectric resonator antennas (DRAs) of rectangular cross-section, fed by a microstrip line. The array combines DRA technology with multi-layer printed technology. A 320 element array with integrated low noise amplifiers and four-bit digital phase shifters is under development. The array offers high gain, wide pattern bandwidths, and electronic beam steering capability.
