What is difference between broadside and Endfire array antenna?
What is difference between broadside and Endfire array antenna?
In a wider sense, the end-fire array is a linear or planar antenna whose direction of maximum radiation is along the line or in the plane of the array….End-fire array.
| S.No. | Broad side array | End fire array |
|---|---|---|
| 9. | The radiation pattern of the broadside array is bidirectional | The radiation pattern of the broadside array is Unidirectional |
Which pattern is broadside array pattern?
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.
What is the radiation pattern direction of broadside array antenna?
In broadside array, the direction of the maximum radiation is perpendicular to the axis of array; while in the end fire array, the direction of the maximum radiation is along the axis of array. Thus in the end fire array number of identical antennas are spaced equally along a line.
Is broadside a driven 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.
What kind of arrangement is a 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:
Why do antenna arrays have a bidirectional radiation pattern?
The reason for its bidirectional radiation pattern is that it radiates in both direction along the broadside. Thus, we can say, a broadside arrangement is the one whose principal direction of radiation is normal to the array axis as well as the plane of element placement.
How are dipoles formed in a broad side array?
Antenna 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.
Which is the direction of maximum radiation in a broadside array?
In broadside array, the direction of the maximum radiation is perpendicular to the axis of array; while in the end fire array, the direction of the maximum radiation is along the axis of array. Fig. 3 End fire array
