We propose a novel bowtie radar antenna with a pyramidal reflector, which shows low return loss and high directional gain, capable of covering the whole ultra wideband (UWB) frequency band. The measured return loss is less than −10 dB over 3.0–11.7 GHz, and the radiation pattern is unidirectional with a high front‐to‐back ratio for UWB radar imaging applications. © 2008 Wiley Periodicals, Inc.
