Amplitude may imply a complex signal, including both magnitude and the phase . The electrical losses of an antenna together with its directivity determine the antenna gain . In general, the beamwidth in any plane is inversely proportional to the aperture width in that plane, and directly proportional to the wavelength of the radiation. Polarization on transmit and on receive is determined by the antenna. A signal is attenuated by application of a gain less than unity.
