Abstract

Abstract: The development of 5G New Radio (NR) is widely concerned. In order to solve the problem of working frequency band, a design scheme of frequency reconfigurable antenna module covering 3.5 GHz and 4.9 GHz frequency band is proposed in this paper. It can be applied to 3.4-3.6 GHz band and 4.8-5.0 GHz band, which can meet the application of sub 6GHz band in 5G communication. The antenna module adopts a feed port, a tune stub, and five switches which can realize frequency reconfiguration. In this paper, the analysis of the parameters of the ground plane and the length of the tune stub is given, and the discussions of the S-parameter, the simulated electrical field distributions, the radiation pattern, the voltage standing wave ratio (VSWR) and the Smith chart are also given, which proves the practicability of the proposed antenna. The size of the antenna module is suitable and the performance is excellent.

5G移动终端设备频率可重构天线的新设计

摘要:5G新无线电(NR)的发展受到广泛关注。为了解决工作频段问题，本文提出了一种覆盖3.5 GHz和4.9 GHz频段的频率可重构天线模块设计方案。可应用于3.4-3.6 GHz频段和4.8-5.0 GHz频段，可满足sub - 6GHz频段在5G通信中的应用。天线模块采用1个馈电口、1个调谐存根和5个开关，可实现频率重构。文中对天线的接地面参数和调谐段长度进行了分析，并对s参数、模拟电场分布、辐射方向图、驻波比和史密斯图进行了讨论，证明了该天线的实用性。天线模块尺寸合适，性能优良。
