ABSTRACT:
An improved feed waveguide 15 for an antenna 10 is disclosed which reduces coupling junction phase errors. The improved feed waveguide 15 of the present invention includes first and second slotted parallel walls 35a and 37a along the length thereof. The first wall 35a includes a first elongate slot 27 therethrough having a first longitudinal axis 42. The second wall 37a includes a second elongate slot 32 which is located on the second wall 37a opposite the first slot 27 on the first wall 35a. The second slot 32 has a longitudinal axis 44 which is orthogonal to the longitudinal axis 42 of the first slot 27.
