While it is technically possible to use a Wi-Fi antenna for LoRa communication, it may not always be the most optimal choice. Wi-Fi antennas are designed to operate at specific frequency bands (2.4 GHz or 5 GHz) and are optimized for the characteristics of Wi-Fi signals, such as high data rates and relatively short-range communication.
LoRa operates in different frequency bands (e.g., 433 MHz, 868 MHz, or 915 MHz), and antennas designed for these frequencies are typically optimized for long-range communication with low-power, narrowband signals. While some wideband antennas may cover both Wi-Fi and LoRa frequency bands to some extent, they may not provide optimal performance for either technology.
For the best results in LoRa communication, it’s recommended to use antennas specifically designed and optimized for the LoRa frequency band being used (e.g., 433 MHz, 868 MHz, or 915 MHz). These antennas are typically designed to maximize range, efficiency, and signal quality for LoRa transmissions.
However, if using a Wi-Fi antenna as LoRa antenna is the only option available, it may still be possible to achieve communication, especially for short-range or experimental applications. Keep in mind that the performance may not be optimal, and thorough testing and optimization may be necessary to achieve reliable communication. Additionally, ensure that the antenna impedance matches the LoRa device and transmitter characteristics to minimize signal mismatch losses.
