A Design Method of 4G Broadband Antenna

Abstract

The invention discloses a method for designing a 4G broadband antenna. The method for designing the 4G broadband antenna comprises the steps that the whole frequency band needing to be covered by 4G antennas is divided into several continuous and independent frequency bands, and the laying of the antennas is designed according to the divided frequency bands respectively; a feedback location is designed corresponding to each frequency band, the feedback locations are connected with the laid antennas through switching circuits, and the antennas with different working frequency are connected through the different feedback locations at different frequency bands through the control over the switching circuits. The method solves the problem of the smooth transition of the antennas from a 3G bandwidth to a 4G bandwidth, and the bandwidth of the antenna can be conveniently widened to the coverage requirement of the 4G antennas under the same environment.

Description

technical field [0001] The invention relates to the field of antenna design, in particular to a design method of a 4G broadband antenna. Background technique [0002] 3G commercial use will bring China into the era of mobile broadband multimedia, and evolution and upgrading have become the key words of current mobile communications. For the three major operators, compared with 3G and even LTE, although 2G is still the main profit-making part, in the long run, operators have invested a lot of energy in the upgrade and expansion of 3G and even 4G. LTE has shown unprecedented enthusiasm, and gradually transitioned from the experimental stage to the trial commercial stage. On the other hand, industry chain manufacturers such as chips, testing, terminals, and network equipment have also invested in the R&D and promotion of LTE equipment, and have continuously won LTE network construction contracts around the world. In the LTE stage in the future, FDD-LTE and TDD-LTE technologie...
