Abstract

In this paper a practical demonstration of a new analogue phase conjugating architecture which has the capability of correcting beam pointing error is described. When applied to a retrodirective antenna application the beam pointing error caused by duplex frequency transmission and reception through the same antenna array, can be corrected. The circuit has high detection sensitivity and is capable of operating with received signal levels as low as -130dBm. The features described here will further facilitate the migration of this technology into real life advanced communications scenarios.
