High-precision positioning four-arm helical Antenna

1. The antenna adopts a four-arm spiral structure to ensure that the error between the antenna phase center and the geometric center is small, which can effectively reduce the measurement error caused by the antenna;

2. The antenna has high gain, wide beam pattern, and good reception effect for low elevation angle signals;

3. The antenna is small in size and light in weight, suitable for use on equipment that requires antenna weight, such as the field of drones. The antenna has low power consumption and can effectively ensure the battery life of the equipment.
