For the implementation of high-gain dual-band transmit-arrays, adequate unit-cells have to be designed. The potential difficulty is related to the independent 360° phase wrapping needed at each band to compensate arbitrarily large equivalent path length phase compensation. This points to an intractable number of phase combinations at each band, leading to a possibly very large number of different...
Radio wave propagation from a satellite based emitter to an airborne located receiver is of interest for applications like passenger internet access during a flight, air traffic management or positioning by global navigation satellite systems (GNSSs). Especially for the last two applications that are related to safety-of-life functionality, accurate channel models for software based system testing...
