New Leaky Wave Antenna Based on Stub-Loaded Rectangular Waveguide Partially Filled With Left-Handed Material
A new leaky wave antenna is presented in thispaper,which is based on a stub-loaded rectangular waveguidepartially filled with left-handed (LH) or right-handed (RH)dielectric slabs.The leakage properties of the new antenna arecarefully examined by an approach of combining themultimode network theory with the mode-matching method.Asystematic comparison is given for the leaky characteristicsbetween the antenna filled with left hand material (LHM) andwith fight handed material (RHM).It has been found that theformer is of larger leakage constant than that of the latter one.Extensive numerical results for the radiation characteristics ofthe antennas are given with physical explanations to establishuseful guidelines for the antenna design.
