Abstract
The present application discloses a dual open-ended waveguide (DOEWG) antenna apparatus. The apparatus may include a plurality of radiating elements configured to radiate electromagnetic energy. Each radiating element may have an associated amplitude and phase. The apparatus may further include a waveguide configured to propagate an electromagnetic signal from a waveguide feed to the radiating elements. The radiating elements are arranged in a plurality of doublets. Each doublet includes at least two radiating elements and is coupled to the waveguide via a respective doublet neck. At least one doublet in the plurality of doublets is coupled to the waveguide via a doublet neck that has a first height proximate a first radiating element in the at least one doublet and a second height proximate a second radiating element in the at least one doublet in which the first height is different from the second height.
