Layout proposal (antenna location)

Antenna used PCB UpperCeramicsAntennas are electromagnetic radiation in free space. The position and layout range of antenna is the key to increase data rate and transmission range.

Therefore, the layout of antenna location and routing is recommended as follows:1, Place the antenna in PCB On the edge or corner of a board.2, Make sure there is no signal line or copper foil on each layer below the antenna.

3, Best plan 4 Middle antenna positionyellowHollowed out at the square box to ensure that S11 The impact is very small.
