- Abstract
The use of radio frequency (RF) communications and radar signals with multiarray antennas is increasing. The array antennas used in these applications should be sophisticatedly matched in terms of the phase and amplitude for beam steering. In particular, phase and amplitude matching are the core techniques of cross-eye jamming that is known to cause angle deception in radars and missiles with monopulse sensors, resulting in wavefront distortion. In this study, to improve the beam steering performance of typical transceivers with phased array antennas and generate large angle errors in systems with monopulse sensors, a novel architecture to precisely match the phases and amplitudes of multichannel transceiver array antennas in the dual-frequency band is proposed, and the performance is verified using the fabricated device.
