The disclosure relates to an antenna using a single non-conductive portion and an electronic device including the antenna.
Advances in electronics and communication technologies have enabled development of electronic devices having various functions and shapes. Such electronic devices are convergence devices that can perform one or more functions in combination.
As the functional gap between manufacturers has narrowed significantly in recent years, to satisfy consumer needs, electronic devices are becoming slimmer, while conductive members (e.g., metal frames or metal bezels) are used to increase their rigidity. In the case of an electronic device for communication, at least a portion of the conductive member may be used as the antenna for slimming, which requires improvement in radiation performance.
When the exterior of an electronic device is made of a conductive member (e.g., metal frame or metal bezel) to meet the slimming trend of electronic devices, unlike an injection molded dielectric material, the antenna is not separately designed but at least a portion of the conductive member may be used as the antenna. For example, when a conductive member serving as the side member of the electronic device is used as an antenna, the segment between conductive members may be filled with a non-conductive dielectric material and may be used as an insulation part for electrically disconnecting a specific location of the conductive member. Hence, the electrical length of the antenna from the feeder can be adjusted, enabling the antenna to operate in a specified frequency band.
The antenna may be utilized as a radiator by feeding a unit conductive portion of the conductive member electrically insulated by a pair of non-conductive portions spaced at a given interval. For example, it is preferable to design the antenna so as to cover various low bands required by the operator. However, the unit conductive portion segmented by the pair of non-conductive portions has a limited physical length due to the slimming of the electronic device, and cannot cover various low bands even when a matching circuit or an additional radiator is used. In addition, even when the frequency is shifted in the low band by using a matching circuit or an additional radiator, the performance may be degraded as the frequency shifts to a lower frequency owing to the limitation of the physical length of the conductive portion.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
