Antenna requirements

Antenna requirements for an IoT device using nRF9160 are summarized in the following table. The listed requirements apply to all frequencies supported by the IoT device.

Table 1. Antenna requirements
Parameter Requirement Note
50 Ω impedance, antenna Voltage Standing Wave Ratio (VSWR) <2:1 Recommendation
<3:1 Absolute requirement
50 Ω impedance, antenna Return Loss (RL) >9.5 dB Recommendation
>6.0 dB Absolute requirement
Efficiency >50% Recommendation. Operators may have other efficiency requirements.
Maximum gain 1  
Maximum input power 1 W
