Abstract
Two contiguous half-height waveguides (12, 14) having a common broad wall (16) are provided with a pair of closely spaced equal length slots (20) and a single unbalanced-fed half-wave dipole (24) located parallel to and between the slots, with feed line coupled to the waveguide walls between the slots and provides for both longitudinal and transverse polarization. When the waveguides are excited in phase (even mode), the slots radiate similar to a single shunt slot with a longitudinal polarization. When the waveguides ae excited out of phase (an odd mode), the dipole is the primary radiator, radiating energy in a transverse polarization.
