Abstract :
An interleaved, interelement phase-detecting/phase-shifting retrodirective antenna array for interference reduction is presented. This system uses two independent retrodirective subarrays to form a null in one direction while retrodirecting a beam in another direction, while also eliminating the R4 path loss of previous interleaved architectures. Retrodirectivity as well as null steering is reported at 2.4 GHz.
