What is broadside radiation?

A broadside array is a one or two dimensional array in which the direction of radiation (main lobe) of the radio waves is perpendicular to the plane of the antennas. To radiate perpendicularly, the antennas must be fed in phase.

What is the radiation pattern of broadside array?

Hence the radiation pattern of broadside array is bidirectional and the array radiates equally well in either direction of maximum radiation.

What is the difference between broadside and end fire 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. Thus in the end fire array number of identical antennas are spaced equally along a line.

What is Endfire radiation?

[′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.

What is meant by broadside?

Definition of broadside (Entry 1 of 4) 1a(1) : a sizable sheet of paper printed on one side. (2) : a sheet printed on one or both sides and folded. b : something (such as a ballad) printed on a broadside. 2 archaic : the side of a ship above the waterline.

What are the antenna parameters?

Typical parameters of antennas are gain, bandwidth, radiation pattern, beamwidth, polarization, and impedance. The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction.

What is antenna array explain broadside array?

A broadside array is a type of antenna array which is used to radiate the energy in specific direction to make better transmission. It is a bidirectional array which can send and receive process at both ends (sending and receiving end). The front view of the broadside array is shown below.

What is the radiation pattern of a broadside array when array element axis coincides with the 0 line?

Broadside array is a bidirectional antenna and when axis coincides with 00 then maximum radiation is at 90°.

Is broadside a driven array?

A broadside array is a stacked collinear antenna consisting of half-wave dipoles spaced from one another by one-half wavelengths. This antenna produces a highly directional radiation pattern that is broadside or perpendicular to the plane of the array.

What is spacing between antenna array elements for broadside fire?

The usual dipole spacing will be λ/4 or 3λ/4. This arrangement not only helps to avoid the radiation perpendicular to the antenna plane, but also helps the radiated energy get diverted to the direction of radiation of the whole array.

Is also called as 3 dB bandwidth?

The bandwidth of a filter or amplifier is usually defined as the difference between the lower and upper half-power points. This is, therefore, also known as the 3 dB bandwidth. There is no lower half-power point for a low-pass amplifier, so the bandwidth is measured relative to DC, i.e., 0 Hz.
