Abstract

The invention discloses a monopole antenna array generating vortex electromagnetic waves and a feed system of the antenna array, and belongs to the technical field of wireless communication. The monopole antenna array comprises a dielectric substrate, a grounding surface, a feed system and a monopole array antenna body. The dielectric substrate is circular and insulated, a microstrip circuit printed by a metal material is arranged on the dielectric substrate, the microstrip circuit mainly comprises the 1-to-N path feed system and the monopole array antenna body including N array elements, and 1/4 wavelength metal patches serves as the array elements. According to the invention, a vortex electromagnetic wave generating antenna of a planar structure and small in size and easy to produce and integrate is realized. The complete feed system is designed to solve the feed problems of the array antenna, a required OAM mode can be obtained by only applying excitation to an input port, operation is convenient, and use is simple.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically relates to a monopole antenna array for generating vortex electromagnetic waves and a feeding system thereof. Background technique [0002] With the popularization of smart terminals and the development of mobile Internet applications, the spectrum utilization rate and system capacity have approached the Shannon limit. The contradiction between the expanding capacity demand and the increasing shortage of spectrum resources has become a major bottleneck restricting the development of wireless communication technology. In the field of optics, the transmission capability of optical communication systems has been greatly expanded by utilizing the orbital angular momentum of light beams. Therefore, orbital angular momentum has been introduced from the field of optics to the field of wireless communication as a new technology. Theoretically, it can be proved that t...
