摘要： 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.

摘要： Systems and methods which utilize a symmetrical partially coupled microstrip slot feed patch antenna element configuration to provide highly decoupled dual-polarized wideband patch antenna elements are shown. Embodiments provide a microstrip slot feed configuration in which a slot of a first signal feed is centered with respect to the patch and further provide a microstrip slot feed configuration in which slots of a second signal feed are symmetrically disposed with respect to the center of the patch and at positions near the edges of the patch. The microstrip feed utilized in communicating signals with respect to the slots of the second signal feed is adapted to provide signals of substantially equal amplitude and 180° out of phase with respect to each other according to embodiments. The second signal feed configuration utilized according to embodiments provides partial coupling between the patch and the second signal feed.
