Antenna patterns of largecurrent radiator and closed-loop sensor

An experimental setup of antenna systems for the radiation and reception of ultrawideband nonsinusoidal electromagnetic waves will be described. The radiating antenna is called the large-current radiator and the receiving one the closed-loop sensor. Measured antenna patterns of the large-current radiator and the closed-loop sensor will be presented. The measured antenna patterns are peak-amplitude pattern, peak-power pattern, energy pattern, and slope pattern. Based on the principle of pattern multiplication, the array factor for nonsinusoidal waves is multiplied by the above measured antenna patterns to synthesize antenna beam patterns of an array of large-current radiators and those of an array of closed-loop sensors. The synthesized antenna patterns demonstrate that antenna arrays of large-current radiators and closed-loop sensors are very attractive for achieving good radar resolution.
