Abstract
A communication device and a method for enhancing impedance bandwidth of an antenna are provided. The communication device includes at least one ground, at least one antenna, a current-drawing conductor structure, and at least one coupling conductor structure. The antenna is electrically connected to the ground through a source and generates at least one operating frequency band for transmitting or receiving electromagnetic signals of at least one communication band. The current-drawing conductor structure includes a plurality of conductor elements, where there is at least one mutual coupling portion formed between neighboring conductor elements. The coupling conductor structure has a first conductor portion and a second conductor portion. One end of the first conductor portion is electrically connected to the ground, and another end thereof is electrically connected to the second conductor portion. There is at least one coupling portion formed between the second conductor portion and the current-drawing conductor structure.
