INTRODUCTION: LAB Antenna System Trainer is a versatile trainer. Student can understand the basic principles of EM theory and the directivity patterns of various types of antennas. The fundamental principles of radio waves, and the basic operating action and characteristics of different types of antennas can be studied. TOPICS COVERED :
Study of VSWR (Voltage Standing Wave Ratio).
Study of Impedance.
Study of Antenna gain.
Study of Directional Antenna.
Measurements of Front to Back ratio (FBR)
Study of Radiation pattern: plotting of curve - Manual Rotation.
