EFFECT OF PRESENCE OF DIFFERENT MATERIALS ON PROPAGATION OF RADIO WAVES AT X-BAND
Keywords:antenna, X-band, radio waves, propagation, materials
The propagation of radio waves is affected by many reasons and the foremost reason is the medium it travels through. The properties of medium cause attenuation in the transmitted signal. This paper explores the effect of different materials on the propagation. Materials like metal, RF absorber, wood, plastic, PTFE sheet (synthetic plastic polymer) and fiber reinforced plastic (FRP) are placed between two pyramidal horn antennas at X-band (8GHz to 12GHz). Phenomena like reflection, refraction, diffraction and absorption affect the propagation of waves. The paper propounds the effect of these materials on the signal received at the receiver antenna.
