Directivity Pattern of Line Arrays

Author information unavailable

Abstract

Highly directional acoustic and electromagnetic antennae are often built from linear arrays of omnidirectional transmitting or receiving elements This Demonstration plots the directivity pattern of an unshaded line array of omnidirectional elements steered to the angle with respect to the array axis The patterns have cylindrical symmetry about the array axis The array elements are plotted as white
