Abstract
A waveguide manifold for monitoring the operation of an array antenna. The waveguide is centerfed and has reflecting terminations at either end. The waveguide output is matched to the waveguide as if non-reflecting terminations were at either end of the waveguide. The waveguide input is a plurality of groups of slots wherein adjacent groups have alternating phase. Adjacent slots in each group have alternating polarity. A standing wave created in the waveguide has a plurality of cells of alternating phase. Each slot is located within one of the resonating standing wave cells. The resulting manifold beam forming characteristic will be temperature and frequency independent over a practical range.
