Antenna for use in a wearable device
View Patent ↗An earpiece includes a housing, a first short range transceiver for far field communication disposed within the housing, and a second short range transceiver for near field communication disposed within the housing. The second short range transceiver for near field communications comprises an antenna formed from a plurality of coil turns. There is a battery disposed within the housing. The earpiece further includes a first generally planar printed circuit board disposed within the housing and a second generally planar printed circuit board disposed within the housing. There is a flexible connector between circuit boards. The battery is positioned between the first generally planar printed circuit board and the second generally planar printed circuit board. The antenna is mounted perpendicularly to the plurality of components mounted on the first generally planar printed circuit board to thereby reduce electromagnetic interference.
