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:
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.
Abstract:
A digital camera is capable of performing wireless communication with an external device. The digital camera includes a camera body and a lens barrel assembly mounted to the camera body and comprising a plurality of barrels for accommodating a plurality of photographing lenses, wherein at least one of the plurality of barrels is used as an antenna barrel configured as an antenna for the wireless communication, wherein the antenna barrel is formed from a metal material and comprises at least one slit filled with a dielectric material, so that the antenna barrel emits radio waves to perform the antenna function, and wherein an outer casing of the camera body, which surrounds an outer surface of the antenna barrel, is formed from a metal material so as to operate as a ground of the antenna barrel.
Abstract:
An antenna is provided. The antenna includes a first radiator, a second radiator, a current feeder configured to supply power to at least one of the first radiator and the second radiator, and an adjuster configured to adjust transceiving directions of electromagnetic waves transmitted and received to and from the first radiator and the second radiator to be perpendicular to each other.
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.
