摘要

本文分析了运载火箭S波段遥测应用中不同类型的天线切换方案。基于天线覆盖系数对有和无天线交换的6种不同配置进行了性能比较。交换方案采用两个或四个天线单元。本文还介绍了用于上述分析的S波段微带贴片天线的设计。该天线在2.25GHz时的模拟增益为6.7dB，带宽为162 MHz，中心为2.266 GHz。所有配置的增益分析在2.25GHz下进行。4个天线单元和4路交换的配置显示基于覆盖因子的最佳性能。

Analysis of S Band Antenna Switching Schemes for Launch Vehicle Telemetry Applications

This paper presents the analysis of different types of antenna switching schemes for launch vehicle telemetry applications at S band. Performance comparison based on antenna coverage factor is carried out for six different configurations with and without antenna switching. The switching schemes employ either two or four antenna elements. The design of S band Microstrip patch antenna, which is used as basic antenna element for all these analysis, is also presented. This antenna has 6.7dB simulated gain at 2.25GHz and 10 dB bandwidth of 162 MHz, centered at 2.266 GHz. The gain analysis for all configurations is carried out at 2.25GHz. The configuration with four antenna elements and 4 Way switching shows the best performance based on coverage factor.
