Abstract: This report will introduce a series of high efficiency rectenna antennas based on electromagnetic dipoles, omnidirectional circularly polarized antennas, and extremely high aperture efficiency antenna arrays. Electromagnetic dipole is the basic unit of antenna design. Through the organic combination of electromagnetic dipole antenna, the antenna and array can be applied in different occasions and have different efficiency. Firstly, the report will introduce a series of electromagnetic dipole rectenna based on electrically small orthogonal codirection of Huygens source. The aperture of effective absorption of electromagnetic waves is much larger than its physical size. Second, the report will present extremely high aperture efficiency Huygens source electromagnetic dipole antenna arrays, achieving close to 100% antenna aperture efficiency. Finally, an extremely compact omnidirectional circularly polarized antenna and array based on horizontally placed electromagnetic dipoles with a phase difference of 90 degrees are introduced.
