Analysis of traveling wave antenna using rectangular microstip patch array

In this paper, the leaky wave readiation characteristics of a microstrip rectangular patch array is presented. The reflection and transmission characteristics are analyzed using the equivalent transmission line method. Since the leaky wave is generated from the periodic array, using the Floquet'theorem, leaky wave frequency range is predicted and confirmed by the measured reflection and transmission characterstics of the array. A 17 element microstrip patch array at X-Band is designed and tested. Teh scattering Characteristics show good agreement woth those obtained from the equivalent transmission line analysis. The radiatio characteristics at 10GHz using this method show about 3${\circ}$ shift in main lobe angle compared with measured results.
