First Claim
1. An apparatus comprising:
- a printed wiring board;
a code division multiple access antenna fully integrated within the printed wiring board, wherein the code division multiple access antenna comprises an inverted F antenna and a loop antenna;
a global positioning system antenna; and
a conductor separate from and disposed between the fully integrated code division multiple access antenna and the global positioning system antenna to mitigate coupling between antennas, wherein the global positioning system antenna comprises a global positioning system assembly in close arrangement to the printed wiring board, wherein the global positioning system assembly has a contact to interface to the printed wiring board.

Abstract
The present invention comprises systems and methods for cellular, PCS, GPS and/or Bluetooth mobile communication (e.g., a mobile telephone). The systems and methods employ a fully integrated dual band IFA/loop CDMA antenna for cellular and PCS communication. Fully integrating the CDMA antenna within a PWB provides for mitigation of lumped elements to establish dual banding, and can provide for reduced antenna size, device size, cost and interference form a user'"'"'s hand. The IFA antenna is configured to transmit and receive within the cellular frequency band via a capacitive tap, and the loop antenna is configured to transmit and receive within the PCS frequency band via an impedance matching stub and ground location. The system and methods further employ a firewall to mitigate antenna coupling, and a metal reflector to reduce the electromagnetic reflection, and improve antenna gain and efficiency.
