A retrodirective microstrip antenna array [PDF]
IEEE Transactions on Antennas and Propagation, 1998 A Van Atta retrodirective reflector was designed and developed, using an aperture-coupled microstrip antenna array. This reflector possesses the advantage of reflecting high fields to the source point over a wide range of incidence angles and, owing to the low cost and conformability of the structure, is suitable for applications in intelligent vehicle

Method of Four-Element Retrodirective Cross-Eye Jamming Based on DoA
IEEE Access, 2020 The cross-eye method is commonly used to interfere monopulse radars. To overcome the strict tolerance and the range limitation of the traditional retrodirective cross-eye method and the multi-loop method, a novel four-element retrodirective cross-eye ...

Antenna terminals based on ultra‐compact retrodirective antenna arrays [PDF]
IET Microwaves, Antennas & Propagation, 2017 A novel physical effect of angular super‐resolution based on the direction‐of‐arrival information sampling using highly oscillatory evanescent harmonics in dense antenna array environment is demonstrated theoretically and experimentally. This phenomenon enables realisation of novel, ultra‐compact antenna terminals (ATs) with superdirective radiation ...
