1. A housing for a cavity phase shifter, comprising:
a first part that extends along the longitudinal direction of the cavity phase shifter; and
a second part that is separate from the first part, and which extends along the length of the cavity phase shifter, wherein
the first part comprises a substantially flat first base and first arms that extend from the two widthwise edges of the first base toward the second part;
the second part comprises a substantially flat second base and second arms that extend from the two widthwise edges of the second base toward the first part; and
the first arms and the second arms at least partially overlap and are capacitively coupled to each other to form the first cavity of the cavity phase shifter.
