Design and Implementation of Antenna Virtual Laboratory Based on Visual Basic

Based on the procedure of the hardware equipments in antenna laboratory, a virtual labora- tory system for antennas used in development and test is designed and implemented by use of Visual Basic software. The paper introduces the antenna experiment hardware devices and methods for mea- suring antenna parameters, analyses the virtual lab- oratory system framework and the main design pro- eess, and takes the rhombic antenna as an example to demonstrate the system application in antenna simulation, design, and measurement procedures. The system has been applied to the curricular ex- periment teaching and extra-curricular innovation, which has enhanced the practical abilities of stu- dents and changed the traditional experiment teaching mode.
