Helix
Sub-GHz helix antennas are specialized antennas designed to operate in the sub-GHz frequency range, typically 433 MHz, 868 MHz, and 915 MHz. These antennas feature a helical (spiral) design, which allows them to provide circular polarization, making them highly effective in applications where signal reliability and consistent performance are critical, such as in remote sensing, RFID, satellite communication, and long-range IoT devices.
