Substrate integrated waveguide phase shifter

An analogue variable phase shifter on the substrate integrated waveguide (SIW) technique operating at 26 GHz is proposed which employs varactor diodes, properly coupled to the SIW coupler to achieve a continuous electronic control of the phase shift. A vertical transition between 50 Ohm SMA and SIW is used for direct coupling. And all the connections in the… CONTINUE READING
