Calculation of Impedance Variations at the Transceivers in Electronically Beam-Steered Active Lens Antennas for Space Based Radar

Design specifications require estimates to be made of the impedances presented to the monolithic microwave transceivers being investigated for use in electronically beam-steered active lens antennas for space based radar systems. A method of calculation is explained and applied to active lenses composed of large planar arrays of dipoles on either side of a screening plane upon which the transceivers are mounted and connected by parallel wire lines to the dipoles.
