FEED WAVEGUIDE FOR AN ARRAY ANTENNA

摘要

A 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 35 and 37 along the length thereof. The first wall 35 includes a first elongate slot 27 therethrough having a first longitudinal axis 44. The second wall 37 includes a second elongate slot 32 which is located on the second wall 37 opposite the first slot 27 on the first wall 35. The second slot 32 has a longitudinal axis 42 which is orthogonal to the longitudinal axis 44 of the first slot 27.
