FREQUENCY- AND TIME-DOMAIN PERFORMANCE OF A MINIATURE PLANAR ULTRA-WIDEBAND ANTENNA

摘要

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.
