Abstract
A slotted waveguide array antenna includes a plurality of waveguide elements extending in a parallel side-by-side relation, each having a radiating side including a broad wall formed with a plurality of slots, and an asymmetric ridge. The slots are slanted to the longitudinal axis of the antenna in alternating directions and are spaced .lambda.g/2 apart such as to offset phase reversal between each pair of adjacent slots.
