According to the standard definition, “An arrangement in which the principal direction of radiation is perpendicular to the array axis and also to the plane containing the array element” is termed as the broad side array.
Broadside Antenna Array. A type of arrangement of multiple identical elements that are placed parallelly along the line normal to the antenna axes forms a broadside antenna array. It is known to be a practical antenna array configuration which is most widely used. The figure below represents the broadside arrangement of antenna array:
Broadside array is an array which gives a radiation pattern whose main beam is perpendicular to the axis of the array. In a wider sense, broadside array is a linear or a planar array antenna whose direction of maximum radiation is perpendicular to the line or plane of the array.
LECTURE 13: LINEAR ARRAY THEORY - PART I (Linear arrays: the two-element array. N-element array with uniform amplitude and spacing. Broad-side array. End-fire array. Phased array.) 1. Introduction Usually the radiation patterns of single-element antennas are relatively wide, i.e., they have relatively low directivity.
A broadside array is a one or two dimensional array in which the direction of radiation of the radio waves is perpendicular to the plane of the antennas. To radiate perpendicularly, the antennas must be fed in phase.
Jun 3, 2024 · Some antenna arrays are connected so as to produce several independent beams oriented in different directions simultaneously; phased array radar antennas and cellular telephone base stations are common examples.
2.1 Directivity of a Broadside Linear Array The maximum directivity (which occurs in the broadside direction) of a uniformly excited ESLA can be found as follows. First, the normalizedarray factor is (AF) n= sin(N 2 kdcosθ) Nsin(1 2 kdcosθ). (19) If d≪λ, we can employ the small angle approximation for the denominator, yielding (AF) n≈ ...
