A miniature planar antenna for ultra‐wideband (UWB) applications is presented in this article. The proposed compact antenna consists of a quasi‐self‐complementary structure together with a tapered radiating slot. The optimal design of this type of antenna has been demonstrated to provide an ultrawide 10‐dB return loss bandwidth with satisfactory radiation properties. It also exhibits a fairly small dimension, 19 mm×16 mm in physical size and 0.19λ in electrical size, respectively. A parametric study is conducted to provide insights into the antenna operating mechanism. In addition, the time domain behavior of the proposed antenna is also examined. © 2013 Wiley Periodicals, Inc.
