Types of Antenna Arrays - Broadside, End-Fire, Collinear and …
WEBThe various types of antenna arrays are broadside, end-fire, collinear and parasitic antenna array. In this article we will discuss each one of them in detail.

WEBAntenna Theory - Broad-side Array. The antenna array in its simplest form, having a number of elements of equal size, equally spaced along a straight line or axis, forming collinear points, with all dipoles in the same phase, from the same source together form the broad side array.
Antenna array - Wikipedia
WEBA 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.
WEBFrom the resulting pattern we can see we have a combination of a broadside and a so-called end-firepattern. End-fire patterns produce radiation along the axis of the array, which contrasts to normal to the axis for broadside patterns. Usually, we want a broadside pattern, or and end-fire pattern, or something in between, but not usually both.
WEBLECTURE 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.
WEBThe idea of antenna array design is to make the main lobe of the pattern to be much higher than the side lobes so that the radiated power of the antenna is directed along the main lobe or lobes rather than the side lobes.
WEBNov 15, 2020 · Most arrays operate at broadside (Θ= 0 degrees) because of the expense of individual element phase control. Their beams are aimed with antenna gimbals. A large part of array design has to do with beam shaping which is primarily related to element excitation. Scanning is another story. What makes …

WEBTo illustrate, consider an array of 1 + n elements, the first at the origin and designated by "0". The others are designated by i = 1 n and respectively located at a i . We can find the radiation pattern for the array by summing over the contributions of the separate elements.

WEBSep 16, 2016 · Broadside Array: In broadside arrays (Fig. 6), the direction of the main beam is perpendicular to the axis in which the array elements are arranged. The IEEE standard definition of terms states broadside antenna array as “A linear or planar array antenna whose direction of maximum radiation is perpendicular to …
