ABSTRACT:
A microwave phased array antenna module. The antenna module includes a mandrel having an integrally formed waveguide splitter. Separate electromagnetic wave energy distribution panels that each include DC power, data and logic interconnects, as well as electronic modules incorporating ASICs, phase shifters and power amplifiers, are disposed on opposite sides of the mandrel. Waveguide coupling elements are further secured to the mandrel on opposing sides thereof to couple the electromagnetic wave energy received through an input port of the mandrel with each of the distribution panels. Antenna modules are disposed within openings formed in a second end of the mandrel and electrically coupled via electrical interconnects with the distribution panels. The use of the distribution panels provides ample room for the needed electronics while the use of radiating modules disposed at the second end of the mandrel in a brick-type architecture arrangement relative to distribution panels, enables the extremely tight radiating module spacing needed for V-band operation at up to +/−60° scan angles.
