Effect of inter-elements distance and phase shift excitation on radiation performance of linear, planar and circular arrays antennas □

摘要

During the conceiving of arrays antennas, the problem major that we face is the knowledge of the best inter-elements distance and phase shift between radiating elements that we can used to obtain the best radiating performance. So our goal in this paper is to notice the impact of these two parameters in terms of arrays factors and directivity of different arrays antennas (linear, planar and circular). From the results obtained, we can observed that the inter-elements distance influences directly on the number of side lobes and beams width while the phase shift excitation influences only on the direction of principal lobes. These simulations were made in Matlab software.
