Stub array microstrip line phase shifter

Abstract

Systems and methods which utilizes a stub array microstrip line for providing a phase shifter configuration are shown. A stub array microstrip line phase shifter of embodiments may comprises a microstrip line structure, an isolation structure, and a phase tuning structure cooperative to provide phase shifting of signals passed through the microstrip line structure. A microstrip line structure comprises a stub array microstrip line having a plurality of microstrip stubs provided in association with a slotted ground plane having a plurality of slots. The stub array microstrip line is adapted to provide compensation for capacitance and/or inductance associated with the slots of the slotted ground plane. A phase tuning structure provides coupling of signals transmitted by the stub array microstrip line to the slots of the slotted ground plane for signal phase shifting.
