Abstract
A stack-up configuration for a wireless communication device includes a display and keypad on a front face of a housing for the device. A battery for providing power to the components of the wireless communication device is stacked behind the display. A circuit board that holds processing and RF circuitry for the wireless communication device is stacked behind the battery, with a top surface of the circuit board adjacent the battery. Noisy circuitry on the circuit board is covered by shielding on a back surface of the circuit board. An external or internal antenna is connected to the circuit board at a feed point. The antenna in one embodiment of the invention is stacked behind the circuit board, that is, between a back face of the housing and the back surface of the circuit board. The location of the battery between the display and the circuit board lowers the amount of energy radiating from the wireless communications device in the concerned near field range.
