1. A circuit configured for receiving RF energy distributed in multiple RF frequency bands, the circuit including a multi-band multi-channel (MBMC) matching network, the MBMC matching network comprising:

  • a plurality of T-shaped transmission line matching structures, each T-shaped transmission line matching structure coupled in series to another T-shaped transmission line matching structure,wherein each T-shaped transmission line matching structure includes a first portion, a second portion, and a third portion coupled between the first portion and the second portion,wherein the first portion of a first T-shaped transmission line matching structure within the plurality of T-shaped transmission line structures forms an input of the MBMC matching network, the second portion of a second T-shaped transmission line matching structure within the plurality of T-shaped transmission line matching structures forms an output of the MBMC matching network, and the third portion of at least one T-shaped transmission line matching structure within the plurality of T-shaped transmission line matching structures is couplable to electrical ground.
