This invention discloses a single-tooth electromagnetic bandgap resonant cavity for testing dielectric properties in the thickness direction, belonging to the technical field of dielectric property testing for microwave and millimeter-wave materials. The single-tooth electromagnetic bandgap resonant cavity constructed by this method uses the TE test mode. 10n The electric field direction within the cavity is perpendicular to the material thickness direction, enabling the testing of dielectric properties along the Z-axis. This cavity allows for multi-frequency testing, meeting testing requirements within the 2.5GHz to 110GHz frequency range. With a quality factor greater than 3000, it offers higher testing accuracy when measuring dielectric loss. Compared to a double-tooth electromagnetic bandgap resonant cavity, a single-tooth electromagnetic bandgap resonant cavity is simpler, solving the positioning difficulties caused by the need for strict symmetry in the electromagnetic bandgap structure between the two half-cavities, while also reducing manufacturing costs. Furthermore, one side of the single-tooth electromagnetic bandgap resonant cavity is a smooth metal plate, making sample insertion through the gap more convenient.
