A corrugated waveguide phase shifter and its use in HPM dual-reflector antenna arrays

An analysis, with computations and experimental verification, is given which shows that an axially compressible or extendable thin-wall corrugated metallic cylinder can be used as a phase shifter to achieve /spl plusmn/180/spl deg/ phase control. Employment of such a device in an array of high power microwave (HPM) dual-reflector antennas to achieve maximum in-phase array radiation is then briefly outlined.<
