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 p = 4π A ep λ 2 MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaieYdi9WrpeeC0lXdi9qqqj=hEeeu0lXdbb a9frFj0xb9Lqpepeea0xd9s8qiYRWxGi6xij=hbba9q8aq0=yq=He9 q8qiLsFr0=vr0=vr0db8meaabaGacmGadiWaaiWabaabaiaafaaake aacaWGhbWaaSbaaSqaaiaabchaaeqaaOGaeyypa0ZaaSaaaeaacaaI 0aacdaGae8hWdaNaamyqamaaBaaaleaacaqGLbGaaeiCaaqabaaake aacqaH7oaBdaahaaWcbeqaaiaaikdaaaaaaaaa@448D@
