The single-ring circular antenna array of axial dipoles is analyzed in this paper. Such an array consists of m parallel dipoles, equally spaced on the circumference of a circle whose radius is ρ. The two principal properties with which a designer is concerned are (1) the radiation pattern and (2) the impedance of each element in an array, both of which can be found if the current distribution along the element is known. To synthesize a specified radiation pattern, the voltages at the center of each element must be determined.
