Abstract (300 words maximum)
This research project presents the design and simulation of a 1×2 microstrip patch antenna array featuring adaptive polarization and beam-steering capabilities. The antenna system is designed to receive continuous, real-time water quality data from bacteria monitoring devices deployed in a body of water. Polarization control is enabled using a 6-bit digital attenuator and a phase shifter, while beam-steering capability is provided by phase shifters in the antenna feed system. Since each water quality monitor is not necessarily centered in the antenna's physical field of view, electronic beam-steering enhances the desired signals coming from the direction of a monitoring site while suppressing noise and interference from other directions. Electronic beam-steering also means that the system is not reliant on any mechanical systems to rotate the antenna in a desired direction for better signal reception. The phase shift values for the desired beam-steering directions are calculated using a MATLAB algorithm. A link between MATLAB and CST Microwave Studio has been established, allowing automated data exchange and simulation control. The antenna, designed as an array of multiple elements, provides higher gain than current single-element LoRa gateways, enabling it to receive weaker signals that may be attenuated by adverse weather, terrain, or long distances. This setup demonstrates the feasibility of integrating algorithmic control with antenna systems.
