2.8 Antenna characteristics
The antenna is monopole type of chip antenna. The antenna impedance matching is optimized for 1 mm
– 2
mm mother board PCB thickness. The radiation pattern is impacted by the layout of the mother board.
Typically the highest gain is towards GND plane and weakest gain away from the GND plane. Figures 4
– 6
show the radiation pattern of BLE113 when mounted to the development board.
The typical efficiency of the antenna is 25…35% depending on the mother board layout. Maximum gain is 0.5
dBi.
