Abstract : Loop radiating elements for microwave frequencies which result in balanced power division at the feed points and equi-phase currents in the radiating segments are in the form of an Alford loop design having a kink in the stripline path on the side of a printed circuit board opposite the cross-over to restore equal path lengths on both sides of a central feed terminal. Alternatively, the radiating segments of a loop may be in the form of end-loaded bent dipoles which are dual-fed on diametrically opposite points of the loop with equi-phase and amplitude signal. The result is loop radiating elements which have an axial null with a symmetrical doughnut radiating pattern.
