In this study, the dual‐reverse‐arrow fractal (DRAF) geometry is applied to the sides of a slotted microstrip triangular patch to design ultra‐wideband (UWB) antenna with a coplanar waveguide (CPW) feed with and without notch bands. It is shown that the proposed DRAF geometry has the capability of both reducing the antenna size, but without decreasing its bandwidth and also maintaining the other antenna radiation characteristics. It is shown that the antenna is miniaturised by 40% compared with the simple triangular patch. Furthermore, in order to prevent any interference of the proposed antenna with the wireless system of high performance radio LAN (HiperLAN)/2, a notch band is created by cutting two similar slots in the T‐shaped CPW‐feed. Such an antenna has applications in UWB systems. Two prototype DRAF antennas are fabricated and measured, which verify its desirable features.
