EMBEDDED ANTENNA DEVICE FOR ELECTRONIC COMMUNICATION DEVICE

摘要

The present invention relates to an embedded antenna device for an electronic communication device, and the embedded antenna device comprises: a substrate which includes a ground region and a non-ground region; an antenna radiator which is disposed in the non-ground region of said substrate, and is fed to a feeding portion positioned on said substrate; and a transmission line which is split from said antenna radiator, and is disposed in the vicinity of said ground region in order to have a certain length and a certain width, wherein the transmission line is coupled with the ground region to control reactance such that the antenna radiator can be operated in at least one desired band.
