A double wide-area magnetoelectric dipole base station antenna for 5g communication

Abstract

The invention provides a double-wide magnetoelectric dipole base station antenna applied to 5G communication, which includes a magnetoelectric dipole, which is composed of four horizontally polarized units with the same structure, arranged in a cross shape orthogonally, feeding The structure is located at the center of the four horizontal polarization units for coupling and feeding; the reflection floor is composed of a dielectric plate, and the four horizontal polarization units and the feed structure are arranged at the center of the reflection floor. The invention selects two pairs of orthogonally placed magnetoelectric dipoles, so it has good orthogonal horizontal polarization performance. Two pairs of magnetoelectric dipoles placed orthogonally have good symmetry, both use inclined reflective ground and inclined radiation patches, which can achieve good wide H-plane radiation performance, and each pair of magnetoelectric dipoles Both are connected with horizontally polarized additional units of different heights through bent short-circuit walls, so that the antenna can cover two frequency bands of 3.3-3.6GHZ and 4.8-5.0GHz respectively, and achieve good impedance matching, and make the overall structure more compact.

[0002] With the continuous advancement of urbanization, the population density of cities is getting higher and higher, and the communication system urgently needs to be expanded. The number of corresponding base station antennas is also increasing, resulting in increasingly scarce site resources for base stations. In the design of base station antennas , the design of dual-polarized and double-width H-plane antennas has attracted the attention of scholars and experts. However, due to the limitations of the antenna structure, it is largely difficult to solve the problem of antenna miniaturization due to the large size of the antenna.

At the same time, due to the inherent radiation performance of the dual-polarized double-width H-plane antenna at this stage, its radiation gain performance is greatly limited, and it is difficult to achieve high-gain and excellent performance.
