Claim 16:
17. A method for performing phase-shifting, the method comprising:
closing a first switch coupled between a first switchable ground plane and a first ground element, wherein the first switchable ground plane and the first ground element are disposed on a first metal layer of a device;
opening a second switch coupled between a second switchable ground plane and a second ground element, wherein the second switchable ground plane and the second ground element are disposed on a second metal layer of the device; and
transmitting, via a first signal conductive line, a first signal while the first switch is closed and the second switch is opened, wherein the first signal conductive line is disposed on a third metal layer of the device,
wherein the first, second, and third metal layers are spaced apart from each other; and
wherein the second switchable ground plane is spaced apart from the first signal conductive line by a greater distance than the first switchable ground plane.
