end-fire array
end-fire array[′end ‚fīr ə′rā] (electromagnetism) A linear array whose direction of maximum radiation is along the axis of the array; it may be either unidirectional or bidirectional; the elements of the array are parallel and in the same plane, as in a fishbone antenna. Also known as end-fire antenna. end-fire array The effect of array length on the directional characteristic of an end array in which the individual radiators are spaced λ/4 and radiate uniformly in the plane of the paper.A linear or cylindrical antenna array that emits its radiation from one end. In this arrangement, the maximum radiation is along the axis of the array. The end-fire array consists of a number of identical equally spaced antennae arranged along a line and carrying current of equal amplitude. The individual antennae are so excited that there is a progressive phase difference between adjacent antennae expressed in wavelengths.AcronymsSeeEFA |
