Learn about different types of antenna arrays, such as broadside, end-fire, collinear and parasitic, and their characteristics, applications and radiation patterns. A broadside array is a practical arrangement of multiple identical elements that are placed parallelly along the line normal to the antenna axes.
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.
Broadside Arrays. A broadside array is shown in figure 4-26, view A. Physically, it looks somewhat like a ladder. When the array and the elements in it are polarized horizontally, it looks like an upright ladder. When the array is polarized vertically, it looks like a ladder lying on one side (view B).
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.
Learn how to calculate and plot the array factor and the radiation pattern of a linear array of isotropic elements. See examples of equally spaced and unequally spaced arrays, and how they depend on the number of elements and the phase shifts.
