Phase shift circuit and antenna device comprised of at least one movable dielectric body overlapping with an intersecting part of a conductor

A phase shift circuit for changing a phase of a signal comprising:

• a first dielectric body and a second dielectric body opposed to each other;
• and
• a first conductor disposed between the first dielectric body and the second dielectric body,
• wherein the first conductor is provided with an intersecting part extending in a direction intersecting with a longitudinal direction of the phase shift circuit,
• each of the first dielectric body and the second dielectric body is provided with an overlapping part overlapping the intersecting part of the first conductor, and
• an overlapped area between the intersecting part and the overlapping part is changed as the first dielectric body and the second dielectric body are moved in the longitudinal direction of the phase shift circuit,
• wherein the first conductor has a signal input end on one longitudinal end side, a signal output end on another longitudinal end side located opposite to the one longitudinal end side, and a line connecting the signal input end and the signal output end,
• wherein the line includes
• the intersecting part which is a linear line extending in a direction perpendicular to a longitudinal direction of the phase shift circuit;
• and
• a plurality of connecting parts which are linear lines connected to the intersecting part extending in a direction parallel to the longitudinal direction of the phase shift circuit;
• and
• wherein the plurality of connecting parts includes
• a first connecting part which is connected to the signal input end and extends from the signal input end to the intersecting part;
• and
• a second connecting part which is connected to the signal output end and extends from the signal output end to the intersecting part.
