Abstract
A system and method for determining the minimum number of radiating elements required to achieve desired operating characteristics for a circular array of radiating elements. In one embodiment, the present invention determines the number of radiating elements required to space the radiating elements about the periphery of a circle such that a circular array of radiating elements is generated. The radiating elements are spaced apart from each other by a distance which is related to the wavelength of radiation at which the radiating elements operate. The present invention evaluates the maximum and minimum electric field strength generated by the circular array of radiating elements. By comparing the maximum field strength to the minimum field strength, the present invention measures the maximum ripple generated by the circular array of radiating elements. The maximum ripple generated by the circular array of radiating elements is then compared with a predetermined acceptable ripple level. The present invention adjusts the number of radiating elements spaced about the periphery of the circle until the maximum ripple generated by the circular array of radiating elements is less than or equal to the predetermined acceptable ripple level. In so doing, the present invention determines the minimum number of radiating elements required to achieve desired operating characteristics for the circular array of radiating elements.
