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.
