Ruggedized low-relection/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.

1. A radio frequency (RF) transmission-line structure, comprising:
a parallel-plate transmission line formed from a first conducting plate and a second conducting plate, the second conducting plate spaced apart from the first conducting plate and substantially parallel to the first conducting plate; a support member having a first part and a second part, the first part connected to the first conducting plate and the second part connected to the second conducting plate, the support member operative to maintain a fixed mechanical spacing between the first conducting plate and the second conducting plate; and at least one feature configured to isolate or suppress RF interaction of the support member with RF fields within the parallel-plate transmission line; and a rotatable member coupled to the support member, the rotatable member enabling rotation of the first conducting plate relative to the second conducting plate.
