Abstract
An antenna and emission filter are provided. The antenna includes a substrate; an emitter on a substrate wherein the emitter is configured to emit electromagnetic signals; a feeding portion connected to the emitter; and an emission filter comprising a plurality of emission filter cells formed on the substrate in order to filter a surface wave caused by the emitter, wherein each of the plurality of emission filter cells comprises an inductor pattern portion electrically connected with an adjacent emission filter cell to form an inductor; and a capacitor pattern portion distanced from the adjacent emission cell to form a capacitor.
