| Abstract: |
| Shipborne tri-band beam waveguide antenna is designed to satisfy the need of de
ep-space TT&C tasks. By computing beam inconsistency and gain loss for
each band in four different conditions,the impact of electrical axis inconsiste
ncy on performance is analyzed in simultaneous operation at S/X/Ka-band. Sugges
tions for high frequency tracking are given,which is meaningful for practical ap
plications. |
