![]() Λ = Signal wavelength in meter (m) = c/f (where f = signal frequency, C = speed of light = 2.998 × 10 8) It is because of radiation resistance of the antenna will increase when wavelength (λ) increases.Īs per antenna theory, the relation between the gain (G) of the antenna and antenna aperture (Ae) is given by: ![]() The gain of the antenna represents the maximum radiation intensity in a given direction (or absorbs incident power from that direction) when compared with a theoretical isotropic antenna.Īlso, the gain of the antenna will decrease when increasing the wavelength (λ) of the signal. Thus, if the effective antenna aperture increase, the gain of the antenna will increase. ![]() The effective antenna aperture (Ae) of an antenna is the area presented by the antenna to receive or transmit the electromagnetic wave.
