Abstract
An embodiment of passive phase shifter comprises a ground shield, a pair of ground walls electrically connected to the ground shield having a first height above the ground shield; and a signal line positioned between the ground walls and electrically isolated from the ground shield. The signal line may comprise an intermediate signal line separated a second height above the ground shield; a top signal line separated from the intermediate signal line at a third height above the ground shield and electrically connected to the intermediate signal line by one or more conductive vias; and a plurality of blocks positioned between and electrically isolated from the intermediate signal line and the top signal line.

A passive phase shifter comprising:
- a ground shield;
- a pair of ground walls electrically connected to the ground shield, the ground walls having a first height above the ground shield;
- and
- a signal line positioned between the ground walls and electrically isolated from the ground shield, the signal line comprising;
- an intermediate signal line separated a second height above the ground shield;
- a top signal line separated from the intermediate signal line at a third height above the ground shield and electrically connected to the intermediate signal line by one or more conductive vias;
- and
- a plurality of metal blocks positioned between and electrically isolated from the intermediate signal line and the top signal line;
- wherein the ground shield comprises a plurality of elongate slots extending perpendicular to a longitudinal axis of the signal line;
- and
- a first and a second metal block of the plurality of metal blocks are electrically coupled in a first pair;
- and
- the first pair of metal blocks and a second pair of metal blocks are electrically connected to a first switch, the second pair of metal blocks comprising a third metal block and a fourth metal block of the plurality of metal blocks.
