Reconfigurable Pixel-Layer Isolator for Frequency-Tunable On-Frequency Repeaters

Daniel Rodrigo Lopez

The maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters is presented. The scattered fiel ...
