Abstract : This report proposes and demonstrates a direction finding scheme utilizing an array of electrically small antenna elements located on a metallic circular cylinder of modest electrical size. The investigation was accomplished with the aid of a digital computer and two numerical techniques for analyzing electromagnetic radiation problems. By correctly combining the inputs of properly oriented radiators, a system is demonstrated that is capable of angle-of-arrival determination over a frequency band with simple signal processing when the frequency, phase, and polarization of the incident signal are unknown.
