Characteristics of an Ultra-Wide-Band Ultra-Wide-Angle Log-Periodic Antenna

Abstract

A compact ultra-wide-band, ultra-wide-angle log-periodic antenna has been designed by the Mission Research Corporation under a small business innovative research phase II contract with the U.S. Army Research Laboratory (ARL). A proof-of-principle version of the antenna was delivered to ARL. The antenna was evaluated within two days and information returned to the vendor. The calibrations of the antennas included both frequency-domain and time-domain measurements in the High-Power Microwave Anechoic Chamber and the Electromagnetic Research Facility, respectively, and high-voltage-limit characterizations. The appropriate conversion of time-domain and frequency-domain data into gain curves was performed, and the results were discussed. These results are now being applied to the next version of the dual-polarization antenna pair.
