| 摘要 |
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 (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). |
