Investigations of Retrodirective Array Transponders.
Retrodirective arrays, when illuminated by an interrogator signal, transmit a signal back towards the interrogator in the same direction as the incoming signal, without any prior knowledge of the source direction. With a retrodirective array the system efficiently transmits a signal without any …

Tolerance Study of Reflector Antenna Systems (Random Surface Errors, Retrodirective Array, Focal Shift)
The tolerance issue is one of the most important problems in the design and construction of high performance antenna systems. This problem becomes more acute due to the large antenna size, the high operating frequency, and the hostile antenna operating environment. In this thesis, three topics …

Exploitation of Modes in Circular Antenna Arrays
… Further the mode theory was extended to retrodirective arrays. Passive RDCA utilising RL was demonstrated with examples, where novel beam-port interconnections technique was presented. Further cascaded RL configuration was experimentally analysed and demonstrated for retrodirectivity. The …
