Injection molded offset slabline RF feedthrough for active array aperture interconnect

An active radar array, comprising:

• a plurality of radiating elements, each element having at least one radiator port associated therewith;
• a plurality of transmit/receive (T/R) modules, each module associated with a corresponding radiating element, each T/R module having at least one T/R port associated therewith, wherein the T/R port is a coaxial transmission line;
• wherein the radiator port and the T/R port lie on different lattices and are offset from each other in at least two dimensions, and wherein the radiator port is a microstrip transmission line;
• and
• an offset RF interconnection structure for RF interconnection between said radiator port and said T/R port, the interconnection structure comprising a dielectric filled slabline transmission line, the line including a slabline wire center conductor bent to assume one or more bends and form an offset conductor, the conductor having first and second conductor ends, a dielectric body surrounding a portion of the wire center conductor, the first and second wire ends to interconnect with the respective radiator and T/R ports, wherein the first and second wire ends are disposed in respective first and second axes which are not collinear, and an outer slabline conductive housing within which said dielectric body is disposed, said housing comprising first and second generally parallel opposed planar conductive wall surfaces, and the offset RF interconnection structure further includes an in-line section of coaxial line connected to one end of the slabline transmission line and a transition structure between said in-line section and said microstrip transmission line.
