摘要：

A novel ridged SIW leaky-wave antenna (LWA) with controllable side lobe level and low cross-polarization is proposed and fabricated. Longitudinally continuous asymmetric ridges beside SIW sidewalls provide an asymmetric field distribution around the long slot centered on the upper plane of the structure, in way that the slot can radiate. An accurate transverse equivalent network analysis is presented for calculating the properties of the proposed LWA. The wavenumbers of the leaky-mode are calculated theoretically and numerically. The designed ridged SIW LWA shows a good SLL and cross polarization. Measurement results are also consistent with the simulation results.
