The Yagi array allows a significant increase in antenna gain (expressed in dBi or Db over isotropic) by the simple addition of parasitic elements to a dipole or folded dipole.

What is an array and explain its advantages and disadvantages?
what is array? explain with its advantage.
What advantage does the Java ArrayList class have over the Arrays class?
The biggest advantage of an ArrayList is that it can expand in size to fit more data. So, if you don't know how many data values you are going to have, you can construct an ArrayList. Whenever you use the add() method, the object will be added to the ArrayList, regardless of the current size. An Array does not have this advantage. When you construct an Array of size n, the array will always be that size.
What is the advantage to declare an array?
It is more convenient than other possible ways of achieving the same results.
What are the limitations of a variable over advantage of array?
variable cant occupy contigious memory it may take complexity in storing vast data.this becomes easy on using the array concept....
What is advantage linked list?
Adding or deleting nodes is faster than using an array, however, accessing an individual node requires that you traverse the list starting at the head, which is far slower than an array where you can simply calculate the offset.
Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
What is meant by irregular dimensional array?
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.
How do you swap two adjecent no in array in c?
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
What advantage are there in defining an array size in term of symbolic constant rather than a fixed integer value?
It may be possible to generalise results to other integer values.
What is array literal in as2?
An array literal is a comma-separated list of the elements of an array. An array literal can be used for initializing the elements of an array.
How do you swap rows in 2 dimensional array in Java?
[]temp = array[1] array[2]=array[1] array[1]=[]temp
Why the array is starting from zero?
By design; it makes the compiler's work easier. 1-based array's addressing-function: Address (array, index) = Address (array) + (index-1)*Elemsize(array) 0-based array's addressing-function: Address (array, index) = Address (array) + index*Elemsize (array)
