In this article, the design procedures and radiation characteristics of a compact high‐power antenna are discussed. The antenna is designed to efficiently radiate a high‐power ultrawideband nanosecond bipolar pulse. The fabricated antenna realizes directive radiation and a wide bandwidth of 0.2–3.44 GHz (17.2:1) with dimensions of 300 × 300 × 260 mm 3 (width × height × length). The measured far‐voltage is 4.2 kV when the antenna is excited by a 2.5 kV amplitude bipolar pulse with a 1.3 nanosecond pulse width. © 2015 Wiley Periodicals, Inc.
