Abstract

The invention provides a metasurface magnetoelectric dipole antenna. The metasurface magnetoelectric dipole antenna comprises five rectangular dielectric plates, an electric dipole, a magnetic dipole,a pair of short-circuit posts, a metasurface, a feeding structure and two symmetric arc defect-structure reflection ground, wherein the electric dipole is printed above a first layer of dielectric plate, the magnetic dipole is also arranged above the first layer of dielectric plate, the metasurface is embedded into the top of a second layer, the antenna is used for feeding by a stepped feeding structure placed in the center of the electric dipole, and the two symmetric arc defect-structure reflection ground are printed on an upper surface and a lower surface of a fifth dielectric layer. The antenna is designed to a structure of five layers of dielectric plates, and the profile of the antenna can be effectively reduced; and meanwhile, the metasurface material is embedded to the top of thesecond layer, the electric length is effectively reduced by the characteristic of the metasurface, so that the gain of the antenna can be improved, the height of the antenna is reduced, and the low-profile effect of the antenna is achieved.

Description

[Technical field] [0001] The invention belongs to the technical field of communications, and in particular relates to Xinbo-a metasurface magnetoelectric dipole antenna applied to 2G / 3G / LTE5G stacking of dielectric plates. [Background technique] [0002] Due to the rapid development of modern wireless communication systems, the demand for wide-band antennas with stable gain applied to 2G, 3G, LTE, and 5G communication frequency bands is increasing. In 2015, the World Wireless Communication Conference 2015 stipulated that the 5G frequency band for future communication is 3.4-3.6GHz. On the other hand, magnetoelectric dipole antennas are known to possess many excellent electrical properties, such as wide frequency band, stable gain, good front-to-back ratio, and low cross-polarization. Broadband magnetoelectric dipole antennas can be designed to operate in many wireless communication frequency bands, such as 2G / 3G / LTE frequency bands, WLAN / WiMAX frequency bands and ultra-wide...
