Abstract

In this paper, a new small antenna is suggested for 5G Sub-6-GHz band mobile communication. It can change the channel among the three given bands (called the 3.5-GHz area), as a wide-band antenna is connected to a small multiplexer comprising three metamaterial channel filters. The function of channel selection of this antenna system is experimentally demonstrated to prove the validity of the presented scheme. The channel selection for 5G mobile communication is conducted from (channel 1) through (channel 2) to (channel 3), when TX and RX antennas with gains over 0 dBi and less than -10 dB are located far-field apart (R ≫ 2.1 cm), and result in the transmission coefficient () being the greatest at the selected channel, which is detected by a vector network analyzer.

摘要

本文提出了一种用于5G Sub-6-GHz频段移动通信的新型小型天线。它可以在三个给定频段（称为3.5-GHz区域）之间切换信道，因为一个宽带天线连接到一个由三个超材料信道滤波器组成的小型复用器。通过实验证明了该天线系统的信道选择功能，以验证所提出方案的有效性。当增益大于0 dBi的发射天线和增益小于-10 dB的接收天线位于远场距离（R≫2.1 cm）时，对5G移动通信进行信道选择，从（信道1）到（信道2）再到（信道3），并导致在所选信道处传输系数（）最大，这由矢量网络分析仪检测到。
