It is a fundamental property of antennas that the receiving pattern (sensitivity as a function of direction) of an antenna when used for receiving is identical to the far-field radiation pattern of the antenna when used for transmitting. This is a consequence of the reciprocity theorem of electromagnetics and is proved below. Therefore, in discussions of radiation patterns the antenna can be viewed as either transmitting or receiving, whichever is more convenient. This applies on… WebThe radiation leaving the Pyrex window in a given direction is received with a horn antenna and rectified in a calibrated crystal detector. To obtain the total emitted power2 in a given microwave fre-quency band, we make an angular scan of the radiation pattern of the transmitter, derive its gain and use the familiar radar formula.2
