  • Device for energizing a non-eccentric in the wide side of a waveguide, and a slotted antenna comprising such a device
    Patent number: 4873528
    Abstract: A rectangular waveguide with one wide side pierced by slots centered on the longitudinal axis of symmetry. The other wide side includes a ridge having a metallic ribbon with two teeth on its edge each of which is symmetrical with respect to an axis and facing a slot to be energized. The slots are .lambda.o/2 long and are 0.7 .lambda.o apart where .lambda.o is the wave length in air. The two axes of symmetry of the teeth are paralell and .lambda.g/4 apart, where .lambda.g is the wave length in the guide.
