An Embedded Wi-Fi Controller in a C band ...

Modern phased array antennas in radar systems are composed of several thousands of transmit/receive modules (TRM), whose correct functioning has remarkable impact on radar performance. It is therefore of fundamental importance to check and monitor main characteristics of active array components; such actions will permit to verify system performance in real time and, if necessary, suitable actions to guarantee them may be actuated. The application presented in the first part refers to a particular application of metamaterial structures inside an open waveguide, whose final purpose is to allow radiation in free space with high efficiency within a wideband well below its cut-off frequency; in the latter an useful application of an embedded WiFi Controller of a phased array antenna.
