1.6G Four-arm Helical Antenna

Started by Admin, October 9, 2021

Posted October 9, 2021

The four-arm helical structure antenna is composed of four helical arms, and the length of each is an integer multiple of a quarter wavelength. The current amplitudes of the feed ends of the four spiral arms are equal, and the phases are sequentially different by 90°. It has a cardioid pattern, a good front-to-rear ratio and excellent wide-beam circular polarization characteristics. It is very suitable for use as a receiving antenna for a satellite positioning system.

Parameter:

Antenna impedance: 50 ohms

Working frequency band: 1.4 ~ 1.68GHz

Size: 23mm*78mm*1.6mm

Weight: 8.4g

Antenna connector: SMA (male)
