Abstract

This research work focuses on the design, analysis and simulation of a multiband Vivaldi antenna at unlicensed millimetre wave ISM band with resonance frequency-band of 55–66 GHz for high capacity 5G communication framework. The simulation of the proposed antenna is carried out using Rogers RT 5880 substrate. The modified noble design of the double-slotted Vivaldi antenna (DSVA) is proposed with few corrugations and grating elements in order to ameliorate the gain and directivity as well as −10 dB impedance bandwidth. The dimension of the proposed antenna is 70×40×1.07 mm3. This design is primarily focused in attaining a miniaturized antenna having good antenna characteristics with minimum weight and cost and simplicity of integration utilizing feed-networks. The proposed Vivaldi antenna provides excellent VSWR of less than 2 and the gain near about 13–15 dB of six obtained resonance frequencies in frequency-band 55–66 GHz which is very much suitable for high-speed 5G communication. The gain of this antenna is far better than some other recent conventional Vivaldi Antennas.

高速5G通信双槽多带Vivaldi天线的设计与分析

本研究工作主要针对高容量5G通信框架，设计、分析和仿真一种无授权毫米波ISM频段55-66 GHz共振频段多频段Vivaldi天线。采用Rogers RT 5880基板对所提出的天线进行了仿真。提出了一种改进的双槽维瓦尔第天线(DSVA)设计，减少了波纹和光栅元件，以改善增益和指向性以及−10 dB的阻抗带宽。建议天线的尺寸为70×40×1.07 mm3。本设计的主要目的是利用馈电网络实现具有良好天线特性的小型化天线，重量和成本最小，集成简单。所提出的Vivaldi天线在55-66 GHz频段内获得的6个谐振频率的VSWR小于2，增益在13-15 dB左右，非常适合5G高速通信。这种天线的增益远远好于其他一些传统的维瓦尔第天线。
