Abstract In this article, a novel and successful design of ultra‐wideband folded loop antenna is proposed and investigated. The antenna is fed by coplanar waveguide directly and can be fabricated easily by employing printed circuit board technology. It is studied both numerically and experimentally. From calculated and measured results, it may be observed that impedance bandwidth of over 130% for return loss lower than −9.54 dB and good omnidirectional radiation performance is obtained. © 2008 Wiley Periodicals, Inc.
