Antenna Design
The pattern from the RF_OUT terminal pad should be designed with 50 ohms impedance and traced with straight lines
(see Figure 7). The RF_OUT signal line should not run under or near the RN-21 module. The GND plane should be on the
side of the PCB to which the module is mounted. GND should be reinforced with through-hole connections and other
means to stabilize the electric potential.
