Abstract :
A highly efficient leaky-wave antenna (LWA) array using a power-recycling series feeding network is proposed. The input power to the antenna array is efficiently recycled within the array elements and completely leaked out before reaching the terminations. Consequently, the array achieves high radiation efficiency and gain while maintaining a reasonable length in the direction of wave propagation. Simulated and measured results validate the proposed concept.
