Problems solved by technology

[0005] Although the applicant has disclosed in the patent document CN110518353A that the miniaturized dielectric cylindrical lens multi-beam antenna (V2.5 version of the artificial dielectric lens) is applied to the high-speed rail, and has achieved the effect of reducing costs, but in this patent document, it is necessary to The horizontal lens single-beam unit and the vertical lens single-beam unit are used as a whole, at least two cylindrical lenses are used, and the use of two cylindrical lenses will inevitably increase its overall size, and its average RSRP, edge RSRP, coverage, dual-flow The proportion of traffic needs to be further increased, and the weak coverage rate needs to be further reduced

Abstract

The invention provides a new type of artificial dielectric lens antenna capable of reducing 5G base stations on a large scale, which belongs to the field of antenna and 5G construction, and includes a cylindrical lens + / -45° dual-polarized single-beam antenna and an elliptical cylindrical lens + / -45° double Polarized dual-beam antenna, which is composed of + / ‑45° dual-polarized single-antenna excitation new artificial dielectric cylindrical lens; wherein, the present invention also provides a method for co-site construction based on the new 5G lens antenna and the existing 5G antenna , Existing 5G antennas include 5G fixed beam antennas and 5G massive antennas (5GmMIMO). The new 5G lens antenna has the characteristics of high gain, wide coverage and low loss, which is better than the 5G fixed beam antenna. Therefore, on the existing 4G site, the new 5G lens antenna can replace the existing 5G fixed beam antenna, which can greatly reduce the independent construction of 5G base stations.

Description

technical field [0001] The invention relates to the field of 5G construction, in particular to a method for co-site construction based on a novel 5G lens antenna and a 5G antenna. Background technique [0002] 5G is a concentrated expression of new network technologies, and base station construction is being deployed on a large scale around the world. But with the construction of 5G network, the challenges it faces also follow. On the one hand, 5G's interconnection of all things, high speed, low latency, and ultra-large capacity requirements increase the energy consumption of base stations several times. The current 5G antenna feeder system adopts the AAU technology integrated with massive multi-antenna (mMIMO). According to the test, the current power consumption of a 5G single station is 3-4 times that of a 4G single station. The main factor for the increase in 5G power consumption. [0003] On the other hand, the 5G frequency band has risen from 2GHz to 3.5GHz, 5GHz fr...
