Cophasal Excitation Of Circular Antenna Arrays, Chang-Keng Kuo

Masters Theses

[From the Introduction]

An antenna array consists of a set of individual radiating elements, each having a current of some amplitude and phase. If the each of the phases is chosen so that there is some direction in space for which the fields from the individual radiators add in phase, the array is said to be cophased, and the excitation is said to be cophasal. This thesis is concerned with some of the characteristics of cophased circular antenna arrays.

By far the most common antenna array is the linear array, in which the elements are equally spaced along …
