REDUCING RF ENERGY LEAKAGE BETWEEN BATTERY AND PCB

摘要

An improved system 100 and method of reducing RF energy leakage from being trapped in a gap (cavity) 178 between a battery 102 and printed circuit board (PCB) 104 in an electronic communications device 106 is provided by a RF shield assembly that can extend between the battery and the PCB. The RF shield assembly can comprise a conductive wrap 168 and conductive foam 170 connected to metal pads 138 and 140 along the ground plane 136 of the PCB 104.

1. A system of reducing radio frequency (RF) energy leakage between a battery and printed circuit board (PCB) in an electronic communications device, comprising:
an electronic communications device having
at least one antenna;a PCB having at least one ground comprising a metal pad;a battery pack comprising at least one battery for energizing said PCB and a casing for at least partially enclosing and insulating said battery;said battery pack being spaced from said PCB and defining a gap between said battery pack and said PCB; anda RF shield assembly providing a RF barrier wall extending between and connecting said battery pack and said PCB for substantially minimizing RF energy in said gap from interfering with performance of said antenna.
