RUGGEDIZED LOW-REFLECTION/HIGH TRANSMISSION INTEGRATED SPINDLE FOR PARALLEL-PLATE TRANSMISSION-LINE STRUCTURES

摘要

A radio frequency (RF) transmission-line structure includes a parallel-plate transmission line formed from a first conducting plate and a second conducting plate. The second conducting plate is spaced apart from the first conducting plate and substantially parallel to the first conducting plate. A support member is attached to the first and second plates and is operative to maintain a fixed mechanical spacing between the first conducting plate and the second conducting plate. The transmission-line structure further includes at least one feature configured to isolate or suppress RF interaction of the support member with RF fields within the parallel-plate transmission line.
