The present invention discloses an antenna with a filter, which comprises a substrate; an antenna device, a filter and a feed end. The antenna device is printed on the substrate; the filter is coupled to the antenna device; the feed end is coupled to the filter. The filter and the antenna device are radiating members printed on the substrate.
A multiband antenna system is provided. The system includes a substrate; an antenna which is disposed on a first side and a second side of the substrate, and produces a resonance in a plurality of frequency bands; a plurality of feeders which are disposed on the first side of the substrate; and a filter which is disposed on the first side of the substrate, is coupled to an end of the antenna, and transfers signals of the plurality of frequency bands output from the antenna to respective feeders of the plurality of the feeders.
An antenna apparatus is disclosed. The antenna apparatus includes a dielectric substrate; an antenna element pattern formed on the dielectric substrate; a grounding pattern connected to the element pattern; a feed line formed on the dielectric substrate, and connected to the element pattern; and a filter connected to the feed line.
