Enhanced Yagi-Uda Antenna for Low-Power, Long-Range (LoRa) and Remote Sensing at 433 MHz

The design and analysis of a Directional antenna which oscillates at 433 MHz is given in the proposed paper, the antenna has been optimized to operate efficiently with a 16.6 dB reflection coefficient. ensuring minimal signal loss and efficient impedance matching. The design exhibits suitable radiation performance for a long-range wireless transmission application with a gain of 6.6 dB. Because of its unidirectional radiation pattern, the antenna maximizes signal strength in a single direction while reducing interference from other directions. We recommend using this antenna configuration for long-distance, low-power communication systems. Reliability and stability are of the utmost importance in applications that use the Internet of Things and remote sensing. The results demonstrate that the antenna satisfies the performance criteria for data transmission in the 433 MHz LoRa frequency range.
