This paper presents a novel surface-wave antenna that realizes a low-profile configuration using a thin patch-loaded grounded slab, which has an in-phase reflection coefficient for plane waves, but no band gap for surface waves. When a dipole antenna is horizontally positioned near this artificial ground plane, it works like a transducer that converts the energy from the feeding probe into surface waves in the ground plane. The propagation and diffraction of the surface waves generate a monopole-type radiation pattern. The attractive antenna height, which is less than 10% of a typical monopole antenna, is desirable for wireless-communication systems. The performance of the surface-wave antenna is demonstrated through both the FDTD simulations and the measured results.
