A new compact slot antenna is presented for UWB applications. The slot in the ground plane is asymmetric which helps in wide band impedance matching. The radiating element is a star shape geometry which is fed by a double stepped co-planar waveguide structure. Two antennas are designed with this geometry. Out of these two antennas one is proposed.

A compact, low profile, dual polarized, ultra wideband, frequency selective surface is proposed. It is designed by using two similar metallic array structures separated by dielectric material FR4. The simulated reflection bandwidth (with transmission < −20 dB) for TE incident wave is 8 GHz from 2.87GHz to 10.87 GHz corresponds to 116%. The unit cell(More)
In this paper, a compact elliptical shaped UWB fractal antenna is proposed. The excitation is done with a double stepped coplanar waveguide feed. The frequency characteristics of proposed antenna consist of ultra wideband properties in the range 2.85 GHz to 15 GHz corresponding to the impedance bandwidth of 136.13%. The measured radiation patterns are(More)
