Abstract :
A transmitting polarisation agile antenna based on injection locked oscillators has been presented. This phase shifting circuitry presents advantageous properties, such as relatively high power, ease of control and continuous phase shift range. A prototype of the system has been manufactured, providing a continuous range of polarisation variation including two linear and two circular polarisations.
