摘要: 本文提出了一种基于人工负磁导率传输线以及多模式融合技术的天线设计，实现了天线的多模、宽带性能。首先基于传统的环天线，在该环天线的二次模对应的电流零点处引入分布式电容，在不影响二次模谐振频率的情况下，基模的谐振频率移动到更高频并与二次模相融合形成一个双模谐振。同时，通过适当选择环天线尺寸及加载的电容值，在所需频段内还产生了一个零模谐振点，从而天线的零模、基模、二次模的谐振频率相互靠近并融合成一个多模谐振，形成了覆盖WIFI 5G、6E频段(5.15~5.85 GHz, 5.925~7.125 GHz)的宽带。并且在不增加天线尺寸的情况下，通过在传统环天线的中间加载一段感性枝节，产生了WIFI 2.4G (2.4~2.485 GHz)低频谐振。最终，该天线实现了WIFI 2.4G、5G和6E频段的全覆盖。
Abstract: This article proposes an antenna design based on artificial Mu-negative transmission-line structure and multimode compression technology to achieve multimode and broadband performance of the antenna. Firstly, based on traditional loop antenna, distributed capacitors are introduced on the current nulls of the second mode of the loop antenna, without effecting the second resonance mode, the fundamental mode moved to higher frequency band and compressed with the second mode, generating a dual-mode resonance. At the same time, by appropriately selecting the size of the loop antenna and the value of loaded capacitances, zeroth-order resonance is generated within the re-quired frequency band, thus, the zeroth-order resonance, fundamental mode resonance, and second mode resonance of the antenna are compressed, generating a multi-mode resonance, which covers the WIFI 5G and 6E (5.15~5.85 GHz, 5.925~7.125 GHz) frequency bands. In addition, without adding additional space of the antenna, an inductive strip was loaded in the middle of the loop antenna, generating a lower resonance in WIFI 2.4G (2.4~2.485 GHz) band. Ultimately, the proposed antenna can operate in the whole WIFI 2.4G/5G/6E frequency bands simultaneously.
