Abstract

The invention provides a magnetoelectric dipole antenna of a metasurface dielectric plate, which comprises a first dielectric layer, a second dielectric layer and a third dielectric layer, and is characterized in that a pair of short circuit columns and a vertical transmission line pass through the three dielectric layers, and the middle of the dielectric layers is a feed structure; and the vertical transmission line and the feed structure are used for feeding the magnetoelectric dipole antenna. According to the invention, the frequency band is expanded through designing a slot of an appropriate shape on an electric dipole, the low frequency of the impedance bandwidth of the antenna ranges from 3.12GHz to 5.92GHz, the high frequency ranges from 7.14GHz to 8.45GHz. The gain fluctuates from6.0dBi to 8.9dBi in the low frequency, and the gain fluctuates from 6.7dBi to 9.6dBi in the high frequency. The magnetoelectric dipole antenna can realize an approximately symmetric directed radiationpattern on two radiation surfaces E, H in the whole working frequency of the antenna. In the invention, the traditional magnetoelectric dipole antenna technologies are combined with metasurface technologies, so that functions such as wide frequency band, high gain and directed radiation of the antenna are realized.

Description

[technical field] [0001] The invention belongs to the technical field of communication, and in particular relates to a magnetoelectric dipole antenna of a metasurface dielectric plate. [Background technique] [0002] In the process of continuous development of antenna information transmission technology, different frequency bands are successively divided for use, and each re-division represents a leap forward in communication technology. From the development of the first generation (1G) to the fourth generation (4G) mobile communication system, we can find that the communication field is gradually moving towards broadband and high frequency. constantly improving. With the continuous improvement of communication frequency and the continuous development of antenna technology, the speed of Internet access is also gradually accelerating. Now mobile phones can realize most of the functions that can only be operated on computers before, such as video chat, mobile games, online tr...
