ABSTRACT:
An antenna device has an antenna part and a filter part combined into a single unit. The antenna part has a radiating electrode formed on a surface of layered dielectric substrates and a grounding electrode formed inside the layered structure. The filter part is formed below the antenna part and includes shield electrodes, capacitor electrodes and coil electrodes. A feed point on the antenna part and an input section of the filter part are electrically connected to each other through a roughhole, and external electrodes are formed on side surfaces of the multi-layered structure of the dielectric substrates, connecting the grounding electrode of the antenna part and the output section of the filter part. A slot electrode having a slot formed therethrough and a strip line extending perpendicularly to the slot may be inserted between the radiating electrode and the grounding electrode of the antenna part.
