## What is Endfire array?

: a radio antenna with strong directional properties consisting of a number of antenna elements arranged in a line.

## What is broadside array and Endfire arrays?

The array is said to be broadside array if the direction of maximum radiation is perpendicular to the array axis. The array is said to an end-fire array if maximum radiation is along the array axis.

What is end-fire antenna array?

An endfire array is a linear array in which the direction of radiation is along the line of the antennas. The antennas must be fed with a phase difference equal to the separation of adjacent antennas.

What is broad side array?

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 are the types of array antenna?

When the signals are in-phase, they combine together to form a signal of additive amplitude. When the signals are counter phase, they cancel each other. The three types of phased array antennas are 1) linear array, 2) planar array, and 3) frequency scanning array.

### What is tapering array?

Array tapering is used to change the directivity pattern. Generally the attenuation in the reject region is made greater and more nearly constant but at the price of widening the major lobe (for the same number of elements and overall array size).

What is the directivity of broadside array?

Explanation: In a Broadside array the maximum radiated is directed towards the normal to the axis of the array. So it is at angle 90°.

What are the types of antenna array?

When the signals are counter phase, they cancel each other. The three types of phased array antennas are 1) linear array, 2) planar array, and 3) frequency scanning array.

## What are various types of antenna arrays?

Types of Arrays

• Collinear array.
• Broad side array.
• End fire array.
• Parasitic array.
• Yagi-Uda array.
• Log-peroidic array.
• Turnstile array.
• Super-turnstile array.

## What is parasitic array?

The array of antennas in which the parasitic elements get the power through electromagnetic coupling with a driven element which is in proximity with the parasitic element is known as a parasitic array. The simplest form of the parasitic array consists of one driven element and one parasitic element.
