Mixer-Duplexer-Antenna Leaky-Wave System Based on Periodic Space-Time Modulation
We present a mixer-duplexer-antenna leaky-wave system based on periodic space-time modulation. This system operates as a full transceiver, where the upconversion and downconversion mixing operations are accomplished via space-time transitions, the ...
