Abstract:
1. An electronic device comprising: a substrate having a conductive area and a non-conductive area; and a built-in antenna, comprising: a first antenna radiator with at least first and second radiating portions arranged within the non-conductive area of the substrate, wherein the first antenna radiator is fed by a Radio Frequency (RF) end of the substrate, and is connected to the conductive area; a second antenna radiator configured to operate at a band different from operating bands of the at least first and second radiating portions of the first antenna radiator, and fed by the RF end in a position adjacent to the first antenna radiator; and a switching element switching to selectively feed the first antenna radiator and the second antenna radiator; wherein the second antenna radiator is a monopole type antenna having a T-shaped output portion; and wherein the first antenna radiator has a first radiating portion for low frequency band operation having an input portion in the shape of an L and an output portion in the shape of a U, and a second radiating portion for higher frequency band operation, oriented perpendicular to a grounding portion connected to near ends of each of the first and second radiating portions.
