摘要：A directivity controllable array antenna with a variable phase shifter is providedwhich is stable and has a small waveform and intermodulation distortion, excellent highpower handling capability and low-loss. In an array antenna with a variable phase shifter,
the variable phase shifter has a transmission line, and a variable capacitance capacitor isconnected to a terminal of a ground side of the transmission line. In the variablecapacitance capacitor, a plurality of variable capacitance elements each using a thin filmdielectric layer whose dielectric constant changes in accordance with an applied voltageare connected between an input terminal and an output terminal, in parallel to eachother with respect to direct current component and in series with each other with respectto high frequency component.
