A multilayer ceramic structure with a photonic bandgap (MC‐PBG) was fabricated by a method of tape casting combined with screen printing. The MC‐PBG structure is a two‐dimensional array with either rectangular or hexagonal metal coils in a ceramic matrix. The metal coils are connected to the base metal layer in the ceramic substrate to form a monolithic body. The surface‐wave dispersion properties of these MC‐PBG structures were measured. A stop band, which is significantly influenced by the symmetrical characteristics of the inductor–capacitor ( LC ) arrays, was found in both the structures in the frequency range of 2.0–3.5 GHz. Because of their effective surface‐wave suppression, MC‐PBG structures can be used as high‐performance antenna substrates to enhance the broadside gain of patch antenna devices.
