The half width leaky wave antenna uses shorting vias to suppress the dominant mode by forming a phase reversal at the symmetrical center of the antenna. The shorting vias causes a small inductance formed by the shorting vias that cause a variation in the main beam direction. Prior to this research the shorting vias had been assumed to form a perfect short and caused errors in the transverse resonance method calculations and main beam direction estimates. Once the spacing of the shorting vias becomes too wide as related to the wave length the dominant mode is no longer suppressed and the transverse resonance method does not properly approximate the performance of the antenna. The results are modeled in the transverse resonance method then corroborated using a Finite Element Boundary Integral and Finite Integration Technique computational electromagnetic methods.
