  • Gain Horn Antennas
    effectively with a dielectric coating. Feed horns, conical horns, rectangular waveguide apertures, slot antennas, slotted waveguides and pyramidal horns are types of gain horn antennas. A lens horn antenna is another variation that uses lens elements to collimate divergent energy and prevent it from
  • Fundamentals of EM waves
    to 1/radius. The Poynting vector (power/area) is given by E x H. Therefore, power density drops as 1/radius2. Electrically large antennas are good sources of plane waves in the laboratory. A large antenna focuses the power, this is called directivity, or directive gain. Here are some large antenna

Typically measured in dBi or dBd. Attenuation: The loss or weakening of a signal through a transmission line, transmission component
