Sensitivity Measurement of a Pattern Reconfigurable Water Antenna in IoT Applications

In this paper, a pattern reconfigurable water antenna is demonstrated for IoT (Internet of Things) applications. A wireless system including the water antenna and LoRa (Long Range) transceivers is set up. The sensitivity measurements of four different scenarios are carried out. The link budget of each scenario is calculated and the performance is evaluated. The results show that the water antenna works well as a transmitter antenna in the system. This work successfully demonstrates the potentials of water antennas in IoT applications.
