Array modeling for mm-wave active integrated antennas

The design of active integrated antennas operating in the millimeter-wave ( mm-wave) range requires a two-fold analysis: on one hand, the electromagnet ic modeling of large planar arrays; on the other hand, the characterization of the active devices. In this paper we face the former task, by presentin g an efficient method for the calculation of the voltages induced on all th e elements of a planar array by the input (gaussian) beam, and the evaluati on of the impedance matrix of the array. These parameters, together with th e modeling of the active devices, allow for a full characterization of the active integrated antenna.
