Abstract
This paper proposes a nonreciprocal array antenna based on spatiotemporal modulation. This approach relies on the drastically different phase response during the frequency conversion processes in the time-modulated antenna element. A prototype linear array composed of a pair of resonant patches is designed and fabricated for proof-of-concept validation. Measured results are in good agreement with simulation. The results show that the proposed array antenna is capable of providing versatile radiation performance for transmission and reception, including reciprocal transmission and reception radiation beams, nonreciprocal symmetric transmission and reception radiation beams, and nonreciprocal asymmetric transmission and reception radiation beams, by manipulating the RF signal phase and modulation signal phase.
