Simplified dual-frequency antenna for mobile phone
First Claim
1. A simplified dual-frequency antenna for a mobile phone, comprising a main body and a cover;
- said main body being made of a thin metal conductor that is integrally stamped into a desired shape to include a curved wave coil at an upper end and an elongated contact head at the lower end of said main body;
said curved wave coil including horizontal wave segments and vertical wave segments adapted to two different frequencies of 900 MHz and 1800 MHz, respectively; and
said elongated contact head at the lower end of said main body having a stop ring mounted around a lower portion thereof, said stop ring being integrally provided at a predetermined distance below it with a bolt adapted to screw into an antenna jack provided on a mobile phone; and
said cover being made of an insulating plastic material and having a shape suitable for protectively enclosing said curved wave coil of said main body therein with said stop ring tightly fitted in a lower opening of said cover;
whereby when said elongated contact head is inserted into said antenna jack on said mobile phone and said bolt is fully screwed into said antenna jack, said main body protectively enclosed by said cover is quickly and removably connected to said mobile phone with a lower end of said contact head contacting with a conductive leaf spring provided in said mobile phone, enabling said mobile phone to accurately receive signals.

Abstract
A simplified 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 an elongated contact head. 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 contact head has a stop ring mounted around a lower portion thereof and adapted to tightly fit in a lower opening of the cover. The stop ring is integrally provided at a predetermined distance below it with a bolt. By screwing the bolt into an antenna jack on a mobile phone, the antenna is removably connected to the mobile phone with a lower end of the contact head contacting with a conductive leaf spring in the mobile phone, enabling the mobile phone to receive signals.
