Small electrical planar huyghens source antenna

Abstract

The invention discloses a small electrical planar huyghens source antenna. The small electrical planar huyghens source antenna comprises an upper-layer dielectric substrate, a lower-layer dielectric substrate, an electric dipole, a magnetic dipole, a first excitation strip, a second excitation strip and a coaxial cable, wherein the upper-layer dielectric substrate and the lower-layer dielectric substrate are laminated, the electric substrate is in contact with an upper surface of the upper-layer dielectric substrate, the magnetic dipole is in contact with a lower surface of the lower-layer dielectric substrate, the first excitation strip and the second excitation strip are arranged between the upper-layer dielectric substrate and the lower-layer dielectric substrate, the coaxial cable comprises an inner conductor and an outer conductor, the inner conductor passes through the lower-layer dielectric substrate to be connected with the first excitation strip, and the outer conductor passes through the lower-layer dielectric substrate to be connected with the second excitation strip. Through the abovementioned technical scheme, on one hand, the small electrical huyghens source antenna with a single feeding source is achieved by organically combining the electric dipole and the magnetic dipole by means of a near-field coupling resonant technology; and on the other hand, the huyghens source antenna directly adopts non-balance feeding, namely the single coaxial cable feeds, and other auxiliary feeding structures such as a Balun and a power divider are not needed.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an electric facet Huygens source antenna. Background technique [0002] In the field of antenna technology, due to its compact structure and small size, the electrically small antenna has great application prospects and has received extensive attention and research. However, the electrically small antenna is limited to the working mode of half-wave resonance, and its radiation performance is poor, so it is not suitable for long-distance wireless communication and point-to-point communication technology fields. Commonly used methods to improve the radiation performance of electrically small antennas include using a large floor as a reflector, or using a periodic structure to form an array antenna. However, these methods will increase the size of the antenna, making it difficult to maintain electrically small characteristics. Contents of the invention [0003] The object of th...
