Abstract :
A reconfigurable aperture-coupled reflectarray element offering a continuous tuning of the reflection phase is presented. A single varactor load is demonstrated to be sufficient for a full tuning range. Experimental validations are reported for the measured reflection phase of an X-band reflectarray element.
