This letter presents a compact directive antenna to radiate a high-power ultrawideband (UWB) pulse. The proposed antenna is composed of a modified biconical-based radiator (electric dipole), magnetic dipoles, a feedthrough insulator, and a coaxial cable. The electrical size of the antenna is 0.195λL × 0.195 λL × × 0,176λ L (width × height × length), where is the wavelength corresponding to the lowest frequency of the bandwidth. The fabricated antenna realizes a bandwidth of 0.207-2.60 GHz (12.56:1) and a far-voltage of 131.3674 kV with a front-back ratio of 22.72 dB. The antenna is designed to radiate a ±75 kV amplitude bipolar pulse with a 0.83-ns pulse width through the frequency band from 0.207 to 2.33 GHz. [ABSTRACT FROM AUTHOR] |
