Dryad Networks #2227 –LORA sensor and gateways Passive measurements and Tuning -Sensor 14/10/22, Updated 27/04/2023 Olli Talvitie, Matti Lahdenperä, Mikko Leino CONFIDENTIAL Summary 14.10.2022WIRELESS PERFORMANCE MATTERS2 •Sensor prototype with new RF-layout has been measured, and the antenna has been matched. •New matching components are suggested. •The antenna matching and efficiency with the new layout is really good. •Clear improvement compared to the previous layout version can be seen in the total efficiency results. •There have been problems with active testing •The CW-modes of the Sensors are not staying on and different output powers have been recorded from different Sensor prototypes. •It is not clear where the issue is: software or hardware. CONFIDENTIAL Project target/specification 14.10.2022WIRELESS PERFORMANCE MATTERS3 •Dryad Networks Sensor is set to operate in 868 MHz and 915 MHz LORA bands. •High efficiency is required from the Sensor, since it will be placed on a tree, which will decrease its performance. CONFIDENTIAL PassiveMeasurementSetup 14.10.2022WIRELESS PERFORMANCE MATTERS4 •Passive (efficiency & gain) measurements are done at anechoic antenna chamber at Radientum premises in Tampere. •Chamber size is 3x3x5m CONFIDENTIAL S11 MeasurementSetup 14.10.2022WIRELESS PERFORMANCE MATTERS5 •Antenna tuning (S11) was measured with VNA •Measurements were done at free space Cable soldering point Removed for passive measurements CONFIDENTIAL Proposed matching circuit 14.10.2022WIRELESS PERFORMANCE MATTERS6 1,8 pF 15 nH RF Antenna Measured matching circuit •1,8 pF: Murata GJM1555C1H1R8CB01 •15 nH: Murata LQW15AN15NJ00 Suggested component series: •Capacitors: Murata GJM15 •Inductors: Murata LQW15AN_00 CONFIDENTIAL DryadSensorMatching-Potted 14.10.2022WIRELESS PERFORMANCE MATTERS7 LORA bands The proposed matching network provides extremely good matching for the required LORA bands. The measurements have been done, when the Sensor is potted. CONFIDENTIAL DryadSensorTot. Efficiency-Potted 14.10.2022WIRELESS PERFORMANCE MATTERS8 LORA bands The measured total efficiency of the Sensor antenna is extremely high and reflects the matching result. There is clear improvement of around 1 dB from the previous Sensor- version. The measurements have been done in free space (no wood behind the Sensor in anechoic chamber), when the Sensor is potted. CONFIDENTIAL DryadSensorGain-Potted 27.4.2023WIRELESS PERFORMANCE MATTERS9 Measured gain results are in-line with the efficiency results, and the antenna realized gain is above 2dBi in the LoRa-bands. The radiation pattern is typical dipole pattern. LORA bands 870 MHz 915 MHz x z y
