Description

Features：
1. Adopts a four-arm spiral structure to ensure small errors in phase center and geometric
center of the antenna, effectively reduce the measurement errors.
2. High gain, wide beam and good reception effect for low elevation signal.
3. Small size and low power consumption, light weight and wide application, could effectively ensure the battery working time of devices.
