Description
Technical Field
The invention relates to the technical field of antennas, in particular to a low-profile magnetic dipole antenna which can be used for a base station antenna.
Background
In recent years, with the rapid development of modern wireless communication technology, 5G communication systems are widely used in various fields due to their characteristics of high rate and low delay. An important ring constituting a mobile communication system is a base station antenna, but as technology is upgraded, the demand of base stations is increased, more dense arrangement is required, and space resources are lacked, so that the requirements for miniaturization and low profile of the base station antenna are higher and higher.
The basic element in a conventional base station to implement dual polarized radiation is an electric dipole antenna. The electric dipole antenna has the advantages of wide bandwidth and strong polarization stability, and can form higher front-to-back ratio and better beam forming by combining with an antenna reflecting plate, so that the existing design mainly adopts an electric dipole as a structural unit of a base station antenna. This design has certain limitations. Typically, a base station antenna formed by an electric dipole has a high profile height, approximately one-quarter wavelength at the center frequency point of the operating band. In order to achieve miniaturization of the base station antenna, other means have to be taken to reduce the profile.
In 2006, professor k.m. luk et al published "a New Wideband unified Antenna Element", which combines an electric dipole and a magnetic dipole together by using a complementary principle, and designs a magnetoelectric dipole by satisfying certain excitation amplitude and excitation phase conditions. The E-plane and H-plane directional diagrams of the magnetic dipole and the electric dipole compensate each other, and the antenna obtains a wider working frequency band, a higher front-to-back ratio and stable radiation performance. These advantages of magnetoelectric dipoles have led to their widespread use in the design of base station antenna elements in the latter days. However, in order to meet the operation requirement of the electric dipole, the profile height of the magnetic dipole is still high, which greatly limits the future development of the base station antenna.
Because the work of the magnetic dipole which is arranged parallel to the ground is independent of the height from the ground, and the phase difference exists only 90 degrees between the directional diagram of the magnetic dipole and the directional diagram of the electric dipole, the application provides a low-profile magnetic dipole antenna, and the electric dipole can be replaced as a base station antenna radiation unit in the future.
