Antenna and portable device having the same

摘要

An antenna and a portable device having the same are provided. The antenna provided in a portable device includes: a radiator unit housed at one surface of the portable device; and a resonant frequency compensation unit housed at another surface of the portable device facing the one surface and adjusting a resonant frequency of the radiator unit changed by an environment change to a preset resonant frequency. Examples of the environment change include a device color change, and a battery size change.

主权项

1. An antenna provided in a portable device, comprising:
a radiator disposed at one surface of the portable device; and a resonant frequency compensation unit attached to or forming at least part of another surface of the portable device facing the one surface, and having a predetermined dielectric constant set to adjust a resonant frequency of the antenna changed by an environmental condition to a preset resonant frequency, wherein the environmental condition is at least one of an effective dielectric constant of a case with a particular color or material painted thereon, or the presence of a type of battery mounted within the portable device.
