Abstract : A detailed analysis is presented for a circular array of Beverage antennas over a conducting earth. Equations are derived for azimuth and elevation patterns for any number of similar antennas in the array taken any number at a time, spaced in any manner, and summed in any arbitrary manner with or without phasing. The analysis provides both ground wave and sky wave patterns. For sky wave patterns the polarization of the incident field may be linear or elliptical. Calculations show the sector arrays considered so far to have low polarization error. Polarization error is further reduced as beamwidth is reduced.
