Abstract :
A 6 GHz improved rotating field phaser, which consists of a circular waveguide loaded with a ferrite tube containing a metal rod coaxially, is described. In order to design the phaser, the differential phase shifts of the phaser have been calculated by a perturbation method under some assumptions, resulting in good approximate values. The phaser constructed for trial is shown to have an insertion loss of less than 0.6 decibels over an 8 percent frequency band.
