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