Artificial dielectric cylindrical lens-based multi-beam antenna of covering high building

Abstract

The invention provides an artificial dielectric cylindrical lens-based multi-beam antenna of covering a high building. The artificial dielectric cylindrical lens-based multi-beam antenna is formed byhighly integrating a plurality of antenna elements through an artificial dielectric cylindrical lens as a carrier. The artificial dielectric cylindrical lens-based multi-beam antenna comprises a cylindrical lens 1, antenna element groups 2 and a metal bottom plate 3, wherein the cylindrical lens 1 is made of an artificial dielectric material; the multi-beam antenna comprises two same antenna element groups 2; each antenna element group 2 comprises a plurality of antenna elements; the antenna elements are individuals and are fixed on the metal bottom plate 3 to form a whole body; and the two antenna element groups 2 are distributed at the same side of the cylindrical lens 1 and are uniformly arranged into upper and lower lines along the semi-circumference of the cylindrical lens 1. The pitch plane diagram of the antenna has double beams which turn up and incline downwards separately, so that a complicated electric tuning mechanism can be omitted, the problem that the high building cannot receive a mobile signal is solved, and the artificial dielectric cylindrical lens-based multi-beam antenna is especially suitable for intensive user and large data traffic business areas.

Description

technical field [0001] The present invention relates to the field of radio antennas, and more specifically, the present invention relates to a multi-beam antenna for high-rise mobile communication base stations, and the elevation plane pattern of the antenna has double beams. Background technique [0002] With the rapid expansion of market demand in wireless fields such as mobile communication 4G, 5G, MIMO, satellite communication, radar, and electronic warfare, new technical requirements are also put forward for antennas used as wireless entrances and exits. While meeting the requirements of high gain, low sidelobe, narrow beam, and wide beam coverage, it is also necessary to take into account the needs of scanning speed, cost, and environment. The most important thing is that the antenna must be able to carry a large information capacity without increasing its number and site. [0003] The emergence of multi-beam antennas can solve the above-mentioned technical problems. ...

Problems solved by technology

The radiating element irradiates the focusing device so that it radiates at a 360° azimuth angle. The horizontal plane coverage is large, but the blind area is large, the signal strength is weak, and the anti-interference ability is poor. , There is a certain limit to the speed of the network, it is difficult to cover high-rise buildings
