Which of the following statement is true?(a) As the number of elements increase in array it becomes more directive(b) As the number of elements increase in array it becomes less directive(c) Point to point communication is not possible with more number of array elements(d) There is no uniform progressive phase shift in linear uniform arrayThis question was addressed to me during an online interview.This is a very interesting question from N-element Linear Array topic in portion Antenna Array of Antennas

Answer»

The correct ANSWER is (a) As the number of elements increase in ARRAY it becomes more directive

The explanation is: To get a single beam for the point to point communication more number of array elements is used. It increases the directivity of the ANTENNA. An array is SAID to be uniform if the elements are excited equally and there is a uniform progressive PHASE shift.
