Radiation Characteristic and Polarization of Decimeter Waves

The Radiation Characteristic and Polarization of Decimeter Waves is designed to study the radiation characteristics and polarization of a half-wave (λ/2) dipole antenna using decimeter waves. The experiment enables students to observe the directional radiation pattern by moving the receiver around the transmitting antenna and to investigate the polarization of electromagnetic waves by rotating the receiving antenna relative to the transmitter. Manufactured by Atico Export India.

Principle

A half-wave dipole antenna radiates electromagnetic waves with a characteristic directional radiation pattern. The received signal strength depends on the relative position and orientation of the receiving antenna. By rotating the receiver and changing its position around the transmitter, the radiation pattern and the polarization properties of the emitted decimeter waves can be experimentally verified.
