THE RADIATION IMPEDANCE OF A COLINEAR ARRAY OF FINITE CYLINDRICAL RADIATORS

Abstract

The radiation impedance of a finite array of finite cylinders is determined by a boundary value problem technique. The final equations for the radiation impedance are stated without restriction on cylinder length or radius, cylinder spacing, or on the amplitude and phase of the radial velocity of the cylinders. The derivation is made for the case of each cylinder in the array having a uniform radial velocity over a sector of the cylinder, but the method of solution is not limited to such a velocity distribution. The results of a numerical calculation of the effect of electrical beam steering on the radiation impedance of a specific array are shown to illustrate such effect and the use of the derived equation for radiation impedance.
