Abstract :
A novel leaky wave antenna with double radiation beam composed of left-handed slab loaded hybrid waveguide using planar technology is proposed, and its leaky characteristics are investigated with a method, which the multimode network theory is combined with rigorous mode-matching method. The investigation reveals that the structure supports two leaky modes corresponding to the forward and the backward radiations respectively. It demonstrates that the new leaky wave antenna is of desirable property that can radiate both forward and backward directions simultaneously with quite simple configuration.
