  • Patent number: 7012570
    Abstract: An antenna on a printed circuit board (PCB) with a compensating capacitor. The antenna has a radiator disposed over a first surface of the PCB. Wherein the radiator includes a signal feeding section and a tuning section coupled together at a joint. The tuning section includes a bending portion. Also and, a ground layer with or without a protuding portion is disposed on a second surface of the PCB, wherein the bending portion of the tuning section is overlapping with the ground layer to form the compensating capacitor. In addition, the radiator can also have a short circuit stub section, electrically coupled to the ground layer.

  • Publication number: 20050146466
    Abstract: The dual-band monopole printed antenna of this invention comprises: a monopole printed antenna body to perform resonance in response to a first frequency, with one end of the body connected to feed-in line; a tail; and a short-circuited transmission line connecting the other end of the antenna body and an end of the tail; wherein the short-circuited transmission line forms open circuit at its connection with said antenna body when supplied with a current of the first frequency and wherein the antenna body, the transmission line and the tail together perform resonance in response to a second frequency.
