摘要

在这项比较研究中，观察和分析了七种不同形状的微带天线，包括矩形、椭圆形、三角形、嵌入式馈电、H 型缺口和 E 型缺口，重点是它们在微型卫星中应用全球定位系统（GPS）的适用性。为了进行有意义的比较，研究采用了 GPS 应用中的最佳谐振频率，即 1.57542 千兆赫。所有天线设计都是使用 MATLAB 的天线工具箱生成的，在链路预算分析中假定的零极化损耗的理想条件下，效率均为 100%。结果表明，每种天线形状都具有明显的优势和局限性。其中，圆形和椭圆形贴片天线性能均衡，适合 GPS 应用。然而，椭圆形天线的性能落后于圆形天线，后者被认为是 GPS 应用的最佳选择，能提供出色的各向同性天线增益、回波损耗、电压驻波比（VSWR）和较强的链路预算分析结果。

Microstrip antenna system for communication capabilities applications

In this comparative study, seven different microstrip antenna shapes, including rectangular, elliptical, triangular, inset fed, H-notch, and E-notch, were observed and analyzed, focusing on their suitability for global positioning system (GPS) application in microsatellites. To enable meaningful comparison, the study utilized the optimal resonant frequency in GPS applications, which is 1.57542 GHz. All the antenna designs have been generated using MATLAB’s Antenna Toolbox and are 100% efficient under ideal conditions with zero polarization loss, which is assumed in the link budget analysis. The results show that each antenna shape has been found to offer distinct advantages and limitations. Along with this, the circular and elliptical patch antenna presented a well-balanced performance, which is suitable for GPS applications. However, the elliptical shape falls behind the circular shape, which was determined to be the most optimal choice for GPS application, providing excellent isotropic antenna gain, return loss, voltage standing wave ratio (VSWR), and strong link budget analysis results.
