Abstract
In this study, a new simple method for design and implementation of rectangular waveguide leaky wave antenna with the longitudinal long slot is presented. In this method which has been done using HFSS, firstly, the waveguide attenuation is calculated based on the position of the slot in relation to the waveguide broad wall. Then the desired aperture illumination is fitted to the slot position on the broad wall of the waveguide by MATLAB. Finally, a Taylor-distributed rectangular waveguide leaky wave antenna with 30 dB SLL designed and fabricated in ku band. The good agreement between the simulation and the measurement results for radiated patterns verifies the effectiveness of the presented method.
