An automated antenna pattern measurement system

Radiation pattern is one of the most important characteristics of an antenna. To test any fabricated antenna a measurement system is required. This paper presents an antenna measurement system which measures pattern of antenna using the parameters provided by Vector Network Analyzer with the help of positioning controller. The system is implemented on LabVIEW having user interface to provide parameters and display the antenna radiation pattern. The system frequency measurement varies from 30 KHz to 14 GHz. The performance of system is evaluated by comparing results of proposed system with simulation results in IE3D.
