Abstract
Embodiments disclosed include transmission line phase shifters and methods for fabricating transmission line phase shifters that switch signal and ground conductors to reverse electromagnetic fields in a transmission line structure.
Claims10
A transmission line phase shifter that switches signal and ground conductors to reverse electromagnetic fields in a transmission line structure, comprising:
- a first grounded coplanar transmission line having a first end and a second end;
- a first microstrip transmission line having a first end and a second end, wherein the first end of the first microstrip transmission line is coupled to the second end of the first grounded coplanar transmission line;
- a twin lead line having a first end, a second end, a ground conductor and a signal conductor, wherein the first end of the twin lead line is coupled to the second end of the first microstrip transmission line;
- a second microstrip transmission line having a first end and a second end, wherein the first end of the second microstrip transmission line is coupled to the second end of the twin lead line;
- and
- a second grounded coplanar transmission line having a first end and a second end, wherein the first end of the second grounded coplanar transmission line is coupled to the second end of the second microstrip transmission line.

A method for fabricating a transmission line phase shifter that switches signal and ground conductors to reverse electromagnetic fields in a transmission line structure, comprising:
- coupling an end of a first grounded coplanar transmission line to a first end of a first microstrip transmission line;
- coupling a first end of a twin lead line to a second end of the first microstrip transmission line, wherein the twin lead line includes a second end, a ground conductor and a signal conductor;
- coupling a first end of a second microstrip transmission line to the second end of the twin lead line;
- and
- coupling a first end of a second grounded coplanar transmission line to the second end of the second microstrip transmission line.
