ABSTRACT:
A high-frequency two-dimensional antenna includes a plurality of dual-frequency antennas configured to receive signals having first and second frequencies above the microwave band of the electromagnetic spectrum. The dual-frequency antennas of the two-dimensional antenna are arrayed to an effective length to re-radiate signals at a third frequency, which is down-converted from the first and second frequencies. Each dual-frequency antenna of the two-dimensional antenna includes a plurality of dipole antennas, and a plurality of nonlinear resonant circuits. The nonlinear resonant circuits interconnect the dipole antennas and are configured to permit re-radiation of signals having the third frequency over the effective length. A method of down-converting signals having at least first and second electromagnetic radiation frequencies is also provided.
