| Abstract: | The paper analyzes the performance of the coaxial feeds by FDTD. Firstly, the method of conformal FDTD is
introduced, then the performance of the coaxial feeds is analyzed when inspired by different modes, and the engineering project
is provided to form the sum-mode and difference-mode patterns. The coaxial feeds are important to realize the dual-band feeds
of the reflector antennas. |
