Abstract
An antenna device is constructed such that a short circuit exists between an antenna formed on an outer surface of a dielectric substrate and an input end side resonance electrode of a filter section formed on the inside of the dielectric substrate. An output end side resonance electrode of the filter section and an output electrode are coupled to one another via a capacitance. Accordingly, noise current is not allowed to flow to an electronic circuit, which is connected to the antenna device.
