Abstract :
Presents experimental results obtained for a variable peripheral cavity waveguide feed during the investigation of small reflector antenna configurations suitable for sequential lobing and continuous beam steering tracking operation. The presented results, detailing primary and secondary, copolar, cross-polar and phase characteristics, extends the work previously published and highlights the operational capabilities of the system
