ABSTRACT:
A printed antenna includes a smaller antenna member attached onto the circuit board, one or more greater antenna members attached onto the circuit board and electrically coupled to the smaller antenna member with conductive coupling members and coupled in series with each other, a feed-in terminal electrically coupled to the smaller antenna member, and a ground member attached onto the circuit board and spaced away from the feed-in terminal for a spaced distance for increasing the gain value and the frequency bandwidth of the printed antenna. The ground member may include one or more extensions located beside the feed-in terminal and the smaller antenna member.
