Abstract
A dual-frequency antenna for mobile phone includes an integrally stamped thin metal conductor to function as a frequency-control structure of the antenna. An upper end of the stamped thin metal conductor is a curved wave coil and a lower end thereof is a connector having two hooks. The curved wave coil includes horizontal and vertical wave segments adapted to two different frequencies of 900 MHz and 1800 MHz, respectively. A cover encloses the curved wave coil to protect the coil against impact and deformation. The connector is adapted to insert into an antenna jack on a mobile phone to contact with a conductive leaf spring in the mobile phone, and the two hooks of the connector are adapted to firmly hold the whole antenna to the mobile phone.
