9.4 Antennas
9.4.1 Host Antenna Trace Design
To connect RF signal from the module’s RF pins to the antenna, RF connector, or matching
network, 50 ohm-controlled impedance traces should be used. Vias may be used to transition
the RF from one signal layer to another signal layer.
network, 50 ohm-controlled impedance traces should be used. Vias may be used to transition
the RF from one signal layer to another signal layer.
The following controlled impedance RF traces are allowed:
Surface microstrip
Surface coplanar waveguide (CPWG)
Surface ground-backed CPWG
Embedded microstrip
