Novel semiconductor phase shifters for millimeter‐wave devices

Microwave and millimeter-wave ferrite phase shifters are essential components in phased-array antennas for telecommunication and radar applications. However, the extremely high cost and frequency limitations have limited their use to military applications. In this study, potentially low-cost, miniaturized semiconductor phase shifters are analyzed and compared with their ferrite counterparts. Ferrite-semiconductor composite phase shifters are also envisaged. © 2003 Wiley Periodicals, Inc.
