Wireless Sensor Network (WSNs), LoRa, RF Splitter/Combiner, RF Switch, Coplanar Waveguide (CPWG). Wilkinson Power Divider

This thesis mainly aims to provide bidirectional sensor node link communication with neighboring sensor nodes. The connection between the antennas to create a wireless sensor link is provided by using RF Switch and RF Splitter / Combiner designs. The performance evaluations of these two designs are determined as objectives. Measurements are also taken in the LOS and NLOS conditions. The data obtained from the measurement were evaluated in terms of total cost, energy consumption and maximum distance.
