In this paper, the design and implementation of a compact one-port Ka-band (26.5-40 GHz) vector reflectometer or network analyzer (VNA), operating in full Ka-band frequency range, are presented. The design follows that of a recently developed VNA but with the goal of producing a wideband version. The most critical component of this design is a wideband electronically controlled phase shifter, designed using nonuniformly spaced p-i-n diode-loaded slots incorporated in the broad wall of a… CONTINUE READING
