WebThe gain of a real antenna can be as high as 40-50 dB for very large dish antennas (although this is rare). Directivity can be as low as 1.76 dB for a real antenna (example: short dipole antenna ), but can never theoretically be less than 0 dB. However, the peak gain of an antenna can be arbitrarily low because of losses or low efficiency. WebEfficiency and Directivity Recall that the directivity can be calculated from the measured radiation pattern without regard to what the gain is. Typically this can be performed by …
