Passive Opto-Antenna using Air-Filled Substrate-Integrated-Waveguide Technology

In this contribution, we propose a novel extensive full-wave/circuit cosimulation model to analyze the performance of an opto-electronic fully passive downlink remote antenna unit. The vertical-cavity surface-emitting laser, the optical back-to-back connection, the photodetector, the lumped/distributed matching network, and the air-filled substrate-integrated-waveguide antenna are described in a single, complete model, which also incorporates the spurious radiation by the distributed matching network and any remaining impedance mismatch of the antenna.
