Design of a 12 GHz transmit-array

The aim of the paper is to present a particular antenna structure, working as if it were a transmit-array (double array lens). Due to this working function, the structure consists of a patch array in the reception part, a phase delay for each patch and another patch array in the transmission part. The point in using this device is to place it in front of a particular antenna in order to modify the radiation pattern of the feeding antenna. Finally, measurements of these prototypes are shown. This work is the first step in order to develop a reconfigurable transmit-array in future. In this paper some design criteria, simulation results and prototype measurements have been presented.
