6.3. Internal antenna
Optional built-in antenna. When the customer selects the built-in antenna, the
following rules for the built-in antenna and the overall rules for the placement of the
module are required (see the manual for each module, HF-LPB130 for example):
◆ On the user's PCB, the area corresponding to the red area (8.3x18.4m) in the
figure below cannot be placed and GND
◆ The antenna is far away from the metal, at least 10 mm above the higher
components.
◆ The antenna part cannot be blocked by the metal case
High Flying recommends that the HF-LPB100 module be placed in the following
areas of the user board as much as possible to reduce the impact on the antenna and
wireless signals. Please also consult High Flying's technical support personnel to assist
with the placement of the module and the layout of the relevant area.
