IEVref: 712-02-46 ID: Language: en Status: Standard Term: partial effective area (of an antenna for a given polarization and direction) Synonym1: Synonym2: Synonym3: Symbol: Definition: in a given direction, the ratio of the available power at the terminals of a receiving antenna to the power flux density of a plane wave of specified polarization incident on the antenna from that direction NOTE 1 – If no direction is specified, the direction corresponding to maximum available power is implied. NOTE 2 – In free space, for a given polarization and direction, the partial effective area Aep of an antenna used for reception is related to the partial gain Gp of the same antenna used for transmission, by the equation:${G}_{\text{p}}=\frac{4\pi {A}_{\text{ep}}}{{\lambda }^{2}}$ where λ is the wavelength.
