Abstract

There are different dielectric materials which are used as radome for antenna, fill material, lens for antenna and shielding for microwave devices. Selection of a particular material is a key role in microwave system design. In this paper the performance of Dielectric material is evaluated. This material is made in laboratory using two chemicals namely ECOPUF POLYOL and PUFATE ISOCYANATE, which is termed as "Puff". Using X band waveguide, the scattering parameters of Waveguide when Puff is covered is compared with different standard dielectric material which were loading/covering over waveguide. The use of Puff material as antenna fill and RF circuit potting is evaluated. Change in performance of conical horn antenna, patch antenna and its RF electronics after filling Puff is evaluated. This analysis will help in material selection for antenna /waveguide fill application. Vector Network Analyzer (VNA) was used for recording S parameter, Spectrum analyzer for RF circuitry measurement and thermal oven to evaluate operating temperature range.

基于散射参数的X波段天线与分系统介质填充材料对比分析

作为天线的天线罩、填充材料、天线的透镜和微波器件的屏蔽材料有不同的介电材料。特定材料的选择是微波系统设计的关键。本文对介电材料的性能进行了评价。这种材料是在实验室中使用两种化学物质制成的，即ECOPUF多元醇和puate异氰酸酯，称为“泡芙”。利用X波段波导，比较了不同标准介质材料在波导上加载/覆盖时波导的散射参数。评价了泡芙材料在天线填充和射频电路灌封中的应用。对填充泡芙后圆锥喇叭天线、贴片天线及其射频电子性能的变化进行了评价。这种分析将有助于天线/波导填充应用的材料选择。矢量网络分析仪(VNA)用于记录S参数，频谱分析仪用于射频电路测量，热烘箱用于评估工作温度范围。
