Patent number: 6201501Abstract: An antenna configuration for a mobile communication device. The antenna configuration includes at least a first antenna configured so that the first antenna may be mounted near or between a speaker and a earpiece of a mobile station. In an embodiment of the invention, the first antenna comprises a substantially flat conductor including at least one hole for passing sound from the speaker to the earpiece of the mobile station. The first antenna is configured to receive GPS signals. A second antenna is implemented on the mobile station to transmit and receive cellular transmissions.Type: GrantFiled: May 28, 1999Date of Patent: March 13, 2001Assignee: Nokia Mobile Phones LimitedInventors: Aimo Arkko, Antero Lehtola, Ilkka Pankinaho
