Abstract: Six-port reflectometers based on standard four-port couplers are inexpensive but the designs reported thus far in the literature are either for narrow-band operation or do not meet the optimum design specifications. The analysis, design and tests conducted on three modified four-port structures have resulted in three prototype couplers for use as the building blocks of three prototype six-port reflectometers that are capable of meeting the optimum performance requirements.
