    Abstract: Systems, methods, and circuitries are disclosed for providing a retrodirective array. One example retrodirective array includes a plurality of dual-polarized antenna elements configured to receive a pilot signal having a first polarization and phase conjugation circuitry. The phase conjugation circuitry includes, for each of the plurality of antenna elements, a mixer configured to mix the pilot signal with an LO signal to generate a phase conjugated signal and excitation circuitry configured to generate an excitation signal for the antenna element to transmit the phase conjugated signal with a second polarization that is different from the first polarization.
