    In this paper, a high-gain and low-profile super wideband (SWB) antenna is presented. The proposed design consists of an asymmetric coplanar waveguide (CPW)-fed modified Y-shaped monopole antenna. A parasitic patch in the ending of bowtieshaped leads to improve the impedance match performance. Therefore, a fully PEC reflector is included in order to enhance the gain by combining the output and the reflected waves in the boresight direction. An impedance bandwidth of 124% is obtained (4.2-18 GHz for VSWR less than 2) with a very compact size of 0.15λ0×0.22λ0×0.012λ0. Directional radiation patterns for the E and H-planes are achieved. The realized gain of the proposed antenna is enhanced by 3-6.5 dBi over the operating band, and the total efficiency is more than 85%. All these features make the proposed antenna a good candidate for RADAR and WLAN communications
