The aim of this paper is to introduce a novel 12 GHz radiating design based on the idea of active transmitarray. This structure is a kind of intelligent antenna which consists of two radio interfaces connected through microwave circuitry. A feeding horn is placed in front of the RX radio interface, which is illuminated by an incident wave. The intermediate circuits act on the received electromagnetic signal and conduct it towards the TX radio interface. Here, the electromagnetic waves are resent to open space in the form of propagating wave with specific characteristics. In this paper we present an operating prototype. Relevant measurements of the subsystems as well as complete system measurements are shown and discussed.
