The　design　of　this　subject　is　a　microwave　wireless　energy　transmission　system.　The　system　architecture　and　transmission　efficiency　of　wireless　energy　transmission　are　analyzed,　and　the　antenna　structure　is　designed.　According　to　the　analysis　of　the　system,　the　parabolic　antenna　with　the　same　structure　is　determined.　According　to　the　design　principle　of　parabolic　antenna,　the　size　of　each　part　of　the　antenna　model　is　determined,　the　concrete　structure　is　designed　by　using　the　electromagnetic　simulation　software,　and　then　the　influence　of　the　change　of　the　relative　position　of　the　antenna　on　the　antenna　transmission　efficiency　is　analyzed.　©　2020　IEEE.
