Binomial array is an array in which the amplitudes of the antenna elements in the array are arranged according to the coefficients of the binomial series...
The need for a binomial array is
i) In uniform linear array as the array length is increased to increase the directivity, the secondary lobes also occurs.
ii) For certain applications, it is highly desirable that secondary lobes should be eliminated completely or reduced to minimum desirable level compared to main lobes.

What is microstrip patch array antenna?
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
Is end fire array antenna non resonant antenna?
yes
What are the differences between broadside array and end fire array?
end fire array A combination of identical and equally spaced antenna that radiate along the axis of the axis of the antenna array is known as an end fire array. the elements are fed with a current of equal magnitude but opposite in phase.due to this variation in phase ,the radiation obtained is unidirectional. broadside array when the maximum radiation of an array is directed normal to the axis of array it is known as broadside array. in a broadside array combination a number of identical antennas are set up along a line drawn perpendicular to their respective axis.
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.
Compare binomial array with chebyshev array?
chebyshev has less side lobe level compared to binomial arrays
What is microstrip patch array antenna?
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
Is end fire array antenna non resonant antenna?
yes
What kind of antenna is used in base transceiver station?
I think Printed Antenna ( array microstrip antenna)
What are differences between broadside array and end fire array?
end fire array A combination of identical and equally spaced antenna that radiate along the axis of the axis of the antenna array is known as an end fire array. the elements are fed with a current of equal magnitude but opposite in phase.due to this variation in phase ,the radiation obtained is unidirectional. broadside array when the maximum radiation of an array is directed normal to the axis of array it is known as broadside array. in a broadside array combination a number of identical antennas are set up along a line drawn perpendicular to their respective axis.

What are the differences between broadside array and endfire array?
in received antenna: broadside means the direction of arrival is 90 degree or wave perpendicularly impinges the array. and endfire means the wave comes from the direction along the array axis.

What are the advantage of Yagi-uda array?
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.
