摘要

单脉冲跟踪器以使用和和差辐射模式进行跟踪而闻名，通常以电子方式完成。本工作的目的是建立一个双波段全无源天线阵列与复合右手馈电传输线，以获得和和差方向图。设计了一种双频Wilkinson功率分配器，用于2.6 GHz的同相输出和1.8 GHz时180°的相位差，通过在其中一个输出臂中使用CRLH传输线实现。这是结合在微带馈电系统，以获得和和差模式。利用ANSYS HFSS进行了设计优化。制作了天线阵列，并对和方向图进行了验证。验证差异模式的工作正在进行中。

All-Passive Composite Right/Left-Handed (CRLH) Antenna Array for Sum and Difference Patterns

Monopulse tracker is well-known for using the sum and difference radiation patterns for track, typically done electronically. The objective of this work is to create a dual band all-passive antenna array with composite right hand feed transmission lines to obtain the sum and difference patterns. A dual-band Wilkinson power divider has been designed for inphase output at 2.6 GHz and a phase difference of 180° at 1.8 GHz achieved by using a CRLH transmission line in one of the output arms. This is incorporated in a microstrip feed system to obtain the sum and difference patterns. Design optimization has been done using ANSYS HFSS. The antenna array has been fabricated and the sum pattern has been validated. Work is in progress to validate the difference pattern.
