Abstract

An antenna and an electronic device having the same is provided. The antenna includes a substrate including a ground portion, an external metallic frame of the electronic device, a float ground portion arranged to be connected to the external metallic frame in a state of being disconnected from the substrate, and at least one radiator electrically connected to the float ground portion. Upon being fed with power, the at least one radiator may operate as an antenna radiator, or a section of the external metallic frame may operate as the antenna radiator.

Description

technical field [0001] The present disclosure relates to technologies related to antennas. Background technique [0002] Electronic devices having communication functions have been required to have functions that can be provided with mobile communication services of different frequency bands with a single electronic device while being reduced in size and weight. [0003] In order to meet this requirement, for example, a metal device antenna (MDA) and a bezel antenna have been proposed. MDA uses metal mechanical products as radiators, and frame antennas use metal shells as radiators. [0004] Currently, applying an external metal frame structure has become a design trend of electronic devices, and demands for electronic devices following this trend have increased. Metal frame structures have been applied to external casings of electronic devices, and the problem of degradation in antenna radiation performance has also become serious. Although the antenna is designed to avo...
