1. A system for wireless simultaneous transmit and receive (STAR), the system comprising:
at least one multi-input multi-output (MIMO) radiofrequency (RF) front-end,
each MIMO RF front-end comprising:
an RF-shielded chamber;
a symmetrical pair of arrays comprising a first array configured for communication and a second array symmetrical to the first array and disposed within the RF-shielded chamber; and
a first passive multi-beam beamforming network in operable communication with the symmetrical pair of arrays; and
a second passive multi-beam beamforming network identical to the first passive multi-beam beamforming network and in operable communication with the symmetrical pair of arrays,
each of the first passive multi-beam beamforming network and the second passive multi-beam beamforming network being a Butler-Matrix based true-time delay microwave network, a Rotman lens based microwave network, or a Luneberg lens based microwave network.
