A novel ultra‐wideband elliptical slot antenna is proposed.An elliptical slot is rotated by 45° and excited by a circular patch. Tapered microstrip feeding is used for impedance matching. The structure has multiresonance feature over a wide frequency range, where the simulated bandwidth ratio exceeds 20:1. Due to the limitation of the SMA connector, the experiment on the prototype antenna demonstrated an impedance bandwidth (voltage standing wave ratio < 2) of 165%, or 2.54–26.6 GHZ, 10.5:1. © 2012 Wiley Periodicals, Inc.
