5.3 Antenna Design
The access part of the RF antenna of this product supports the PAD form. The connection between
the module and the main board antenna interface is required to be welded and connected through a
microstrip line or a strip line. The microstrip line or strip line is designed according to the characteristic
impedance of 50 ohm, and the length of the wire is less than 10mm. Reserved

Antenna efficiency
Antenna efficiency is the ratio of the input power and radiant power. Because of the return loss,
material loss and coupling loss of the antenna, the radiant power is always lower than the input power.
The ratio is recommended to be controlled over 40%(-4dB).
