Scanning Lens Phased Array Antennas: Analysis, design and demonstrations at millimeter and submillimeter wavelengths using leaky-wave feeds

Millimeter- and submillimeter wave applications, such as point-to-point wireless communications in beyond-5G scenarios, long-range automotive radars and astronomy and astrophysics science cases from space require antennas with high-gain beams that are steerable. At lower (microwave) frequencies, fully sampled phased arrays with thousands of...
