A ceiling tile antenna for use in wireless local area networks and voice networks. A patch style antenna is manufactured in which the dielectric substrate is the ceiling tile itself, and the radiating element and the ground plane are fixed to the face and back of the tile, respectively. Since the ceiling tile acts as the antenna, the back of the ceiling tile does not have to be routed out to create a cavity for an antenna pod. The sizes of the radiating element and the ground plane are not an issue; therefore no miniaturization of the elements is required. Compared to microstrip antennas, a ceiling tile antenna provides a wider bandwidth and higher gain due to the thicker dielectric substrate used for the ceiling tile construction. Therefore, it is easier to achieve multiple resonances. The ceiling tile used as an antenna can be made from mineral fiber, medium density fiber board, fiberglass, drywall and polyvinyl chloride.
