Study of mutual coupling effect in array of dipole radiators generating different beam shapes

The method of moments solution has been used to study the current distribution and impedance property of a single dipole of finite radius. This method has been extended to investigate the impedance and radiation problem as well as the effect of coupling for an array of radiators, producing a pencil beam or a shaped beam, and excited by specified voltage sources at a given number of ports. Results have been obtained on the impedance seen by the feed and also on the net radiation pattern in a mutually coupled environment.<>
