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.
Abstract:
A multiband antenna apparatus and an electronic apparatus having the multiband antenna apparatus are provided. The multiband antenna apparatus includes: a low frequency antenna which transmits and receives at least one low frequency band signal; and a high frequency antenna which transmits and receives at least one high frequency band signal, wherein the low frequency antenna includes a single wing part which emits an electric wave.
Abstract:
An end fire antenna apparatus built in an electronic apparatus includes a printed circuit board (PCB), at least one main antenna built in the PCB and configured to radiate a radio wave, and a ground plate disposed on a side surface of the PCB, the ground plate being electrically isolated from the at least one main antenna. The at least one main antenna has a pillar shape uniformly extending along a thickness direction of the PCB.
