Abstract: In antenna propagation waves should be guided from leakages and directionality which has became more essential now a days due to number of hurdles which scatters the signal. In this paper we design a leaky lens antenna of UWB frequency and simulate that using CST tool in parallel plate waveguide that works efficiently in high frequency range of 6-30GHz. This approach is totally based on propagation of leaky waves by focusing on the lenses properties. Eventually we increase the gap between the lens and slot for optimal directivity in antenna and then for optimizing the transmission coefficient and minimizing the reflection we use the Matching layer in it. As a result directional radiation will be obtained which is much more achieved than any other antenna of Ultra Wide Band Range and the minimum bandwidth is required which is less than -10dB for radiation.
Keywords: UWB, leaky waves, hurdles, directivity, radiation.
