Lightweight and compact antenna design for navigation radar application

摘要

This paper describes about the antenna design for navigation radar application which has compact dimension and lightweight. Microstrip planar with rectangular patch is selected as an antenna design. A radar antenna is composed of 4 unit antenna module. An antenna module consists of 12 patches that are arranged in vertical and horizontal directions. Antenna feeding is located in the center of antenna module using one SMA connector. The simulation and measurement shows that the antenna design has a performance in accordance with the desired specifications. The antenna design is suitable for the application of navigation radar due to the simplicity in structure, lightweight and ease of fabrication.
