Cavity Backed Spirals Antenna

Brand :ENRICHTEK

P/N :ATBDBS Series

MOQ :1

ATBDBS series cavity backed spirals antenna from ENRICHTEK are specially designed for reconnaissance, orientation, remote sensing and flush installation of aircrafts. This type of spirals antenna can be used as a separate antenna assembly or as a feed for a reflector satellite antenna.

The structure of the cavity backed spirals antenna is compact and light, and it has superior impedance matching and radiation direction control over the whole working bandwidth. It is an ideal tool for amplitude matching, phase and gain tracking. The performance consistency and frequency independence between antennas make it the ideal choice for aircraft detection and receiving systems.

There are two polarization modes of cavity backed spirals antenna: right-handed or left-handed circular polarization. The design of the cavity backed spirals antenna adopts extremely strict environmental standards, and it can work stably and reliably in harsh environment.

Our company can customize cavity backed spirals antenna according to customer's special requirements, especially cavity backed spirals antenna with special requirements for frequency.
