A leaky wave antenna of uniform configuration based on nonradiative dielectric wave guide (NRD) is studied. Non radiative dielectric wave guide is a modification of H-guide suitable for millimetre wavelengths. Wave propagation, power leakage, radiation pattern and frequency scanning feature of this kind of antenna is analyzed. Analysis is held on U band of frequencies using HFSS software
