What is non uniform antenna array?
Non-uniform array means elements of the array. are fed with different amplitudes and different. phases. Types of non-uniform amplitude linear array.
What is a uniform antenna array?
A Uniform Linear Array (ULA) is a collection of sensor elements equally spaced along a straight line. The most common type of sensor is a dipole antenna that can transmit and receive Electromagnetic Waves over the air. Other types of sensors include acoustic sensors that may be used in air or under water.
What is the advantage of using antenna arrays instead of using a single antenna of same type?
An antenna array can achieve higher gain (directivity), that is a narrower beam of radio waves, than could be achieved by a single element. In general, the larger the number of individual antenna elements used, the higher the gain and the narrower the beam.
What are the controlling parameters for designing an antenna array?
The total field of the array can be controlled by five array parameters that are the main design parameters [1]. These are: the geometrical layout of the array elements and their spacings, the excitation amplitude and phase of the individual elements, and finally the pattern of the individual elements.
