A.1. Performance of RWC8201A for LoRaWAN bands
General Description
The recommended operating frequency of the RWC8201A antenna is 700MHz to 8500MHz. When measuring
LoRaWAN devices in RWC7100A Shield Enclosure equipped with RWC8201A antenna as an option, it is necessary
to measure even in the 400MHz band. Therefore, in this application note, the transfer function of the RWC8201A
antenna is measured not only in the 400 MHz band but also in the 900 MHz band. Especially, transfer function
between antennas in the 400-510 MHz and 860-960 MHz bands are dealt with in detail.
Antenna Transfer function
Considering the RWC8201A antenna as a LoRa DUT, place two RWC8201A antennas 7cm apart inside RWC7100A
as shown in Fig.A.1 and measure the transfer function (S21) using Network Analyzer. Through the S21 data, the
flatness and path loss in the band can be confirmed.
