Coplanar Schottky Variable Phase Shifter.
Abstract
A coplanar Schottky variable phase shifter is studied. This device has a simple configuration and is suitable for monolithic integration. The device uses the electronic variability of the depletion layer thickness of the Schottky contact under the coplanar waveguide to change the amount of the phase shift. A periodic structure is introduced to reduce a loss caused by the existing semiconductor material which has a finite conductivity. An integral equation is formulated and solved by the point-matching method. The analysis allows one to predict the phase shift the attenuation in the device. It is shown that such a device can operate at millimeter-wave frequencies with a very small loss. A simple measurement confirmed these predictions. (Author)
