Abstract
A variable phase shifter comprising a coupler including an input port, an output port, a through port and a coupled port and two conducting finite strips exhibiting equal lengths, the first conducting strip being movably coupled with the section of the coupler connecting the input port with the through port and the second conducting strip being movably coupled with the section of the coupler connecting the output port and with the coupled port, wherein displacing the conducting strip relative to the coupler, changes the phase of an output signal from the coupler, relative to the phase of a corresponding input signal into the coupler.
