Abstract: An offset RF interconnect structure for interconnecting an active array radiating aperture to a transmit/receive (T/R) module sub-array, wherein the corresponding input/output (I/O) ports lie on different lattices. The interconnect structure employs dielectric-filled slabline transmission line, which includes a center conductor wire conductor bent to form the offset interconnection between two ports misaligned in two dimensions. The structure includes a dielectric housing that is formed by injection molding about the center slabline wire conductor. The offset interconnect structure can be integrated with an in-line coaxial interconnect structure.
