Abstract

The invention discloses a dual-polarization base station antenna based on photonic crystals. The dual-polarization base station antenna comprises a dielectric substrate. A grounded plate is arranged on the back of the dielectric substrate. Two antenna arrays are arranged side by side at the center of the front through a balun. A photonic crystal reflection panel extends along the vertical direction on the edge of the front of the dielectric substrate. A photonic crystal separation plate extends along the vertical direction on the dielectric substrate between the antenna arrays. Guide plates are arranged on the outer side of the photonic crystal reflection panel and the back of the photonic crystal separation plate. A number of metal patches which are periodically arranged are respectively arranged on the inner side of the photonic crystal reflection panel and positions corresponding to the guide plates on the front of the photonic crystal separation plate. Conductive through holes are arranged between the metal patches and the guide plates. According to the antenna provided by the invention, a broadband effect is realized; through the photonic crystal reflection panel and the photonic crystal separation plate, surface wave propagation can be reduced; coupling between the antenna arrays is reduced; and the total weight of the antenna is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a dual-polarization base station antenna based on photonic crystals. Background technique [0002] With the rapid development of wireless communication technology, it is inevitable that multiple communication standards exist at the same time. At the same time, due to people's concerns about antenna radiation and the conflict of the original base station location, it is becoming more and more difficult to select the site of the new base station antenna. Therefore, , designing a base station antenna that covers a wider frequency band and can adapt to more standards can effectively solve the problem of base station site selection and save a lot of resources. Furthermore, due to the large size and weight of the base station antenna, the cost and difficulty of installation also increase accordingly. Therefore, it is of great practical significance to reduce ...
