The method of synchronising an oscillator by means of injection-locking, and controlling the radiated phase by varying the frequency-controlling parameter as described by Kurwokawa (1973) and Adler (1973) has been the subject of much interest particularly in microstrip beam steering arrays. Here we describe a polarization-agile antenna element employing this method. This antenna is capable of radiating both left and right hand circular polarization and linear polarization in any one of four planes and these polarization states are selected by varying transistor bias voltages.
