Webb16 dec. 2011 · Abstract: An X-band circularly polarized reflectarray antenna with an offset feed is designed, fabricated, and measured. The proposed design features the use of split square ring elements with a modified element rotation technique for phase compensation, which allows the rotation of the slot instead of the element itself. Webb4 feb. 2024 · The (OCF) antenna has done equally well compared to the regular dipole. I just wanted the engineering community to know that with this simple antenna configuration, this multiband ( 7 bands) antenna has almost the same far field strength as the standard dipole, using no passive parts other than a 4:1 balun at the feed point. synergytech automation https://icechipsdiamonddust.com
