Antenna
First Claim
1. A communication device in a radio communication system, the device comprising:
- a first interface for receiving information from a user;
a second interface for transmitting information to said user; and
a built-in multiple band antenna comprising a first part and a second part, said first part being tuned to at least a first frequency band and a second frequency band;
wherein said second part is tuned to at least a third frequency band when electro-magnetically interacting with said first part.

Abstract
The present invention relates to a built-in folded PIFA antenna for a radio communication device (400, 450) and a mobile phone (400) containing the same antenna. The built-in antenna comprises a first part (500) tuned to a first and a second frequency band, and a second part (600) electro-magnetically interacting with the first part (500) and galvanically separated from the first part. While the second part (600) interacts with the first part, the antenna is tuned to a third frequency band. The first part (500) is folded to form a first element (510) and a second element (520), wherein the second element (520) is folded approximately 180 degrees in relation to the longitudinal axis of the first element (520).
