摘要

衬底集成波导(SIW)是一种特殊的天线技术，它既保留了传统矩形波导的低介质损耗特性，又保留了铜表面波的减少特性。在SIW上开发的天线结构简单，易于制造，具有火焰冗余可穿戴性，可集成在墙壁和地板上。为此，设计并分析了一种四分之一模SIW (QMSIW)天线，并将其性能与半模SIW进行了比较。QMSIW经过精确设计，可在40 - 57 GHz范围内高效运行。它旨在增强5G应用的带宽，在55 GHz时最大回波损耗为-36 db。HMSIW结构的三波段谐振频率分别为20.5 GHz、24.7 GHz和27 GHz，回波损耗值分别为-34 db、-14 db和-32.5 db。这两种天线都在5G应用的20 - 72 GHz范围内工作。

Miniaturization and Bandwidth Enhancement of Quarter-mode and Half-mode SIW Cavity-Backed Antenna for 5G Applications

Substrate Integrated Waveguide (SIW) is a special antenna technology which retains reduced copper surface waves and low dielectric loss property of classical rectangular waveguides. The antennas developed on SIW have simple configuration with an ease of fabrication in flame redundant wearable and integration in walls and floors. In this sense a Quarter-mode SIW (QMSIW) antenna has been designed, analyzed and its performance has been compared with Half-mode SIW. QMSIW has been precisely designed to operate efficiently in the range of 40 - 57 GHz. It aims at enhancing the bandwidth for 5G applications with a maximum return loss of -36 db at 55 GHz. HMSIW structure has Triple band resonant frequencies at 20.5 GHz, 24.7 GHz & 27 GHz with the return loss values of -34 db, -14 db & -32.5 db respectively. Both antennas operate in 20 – 72 GHz range of 5G applications.
