Beam-Scanning Reflectarray Based on a Single Varactor-Tuned Element

الملخص EN

A single varactor-tuned element is investigated as effective solution for the realization of reconfigurable reflectarray antennas.

The proposed configuration is successfully implemented for the design of an X-band reflectarray prototype of 3×15 radiators.

A dedicated electronic control board is designed as an integral part of the antenna.

Good performances in terms of beam-scanning capabilities are obtained from measurements.
