Spiral Antennas

Cavity Backed Spiral Antennas

2-18GHz Spiral Antenn with Fiberglass Radome, P/N:LX-20180-FR

A-Imfo’s LX series cavity backed spirals are broadband antennas designed for EMC, surveillance, direction finding, telemetry, and flush mounted airborne applications. These spirals can be used as a separate component antenna or as broadband feeds for reflector type dish antennas.

ALL LX series spiral antennas exhibit an excellent impedance match and radiation pattern control over the broad operating bands in a compact and lightweight package. These spirals are ideally suited for amplitude matching and phase or gain tracking. The unit-to-unit uniformity and frequency independent performance is ideal for airborne monitoring receiving systems. ALL cavity backed spirals are available in RHCP or LHCP. These spirals have been designed to operate in a harsh environment and meet the extremes of the Surroundings Specification.

Cavity backed spriral antennas have been designed to operate in a harsh environment and meet the extremes of the surroundings specification and ideally suite for EMC, surveillance, direction finding, telemetry, reflector feed, system integration, and other applications.

 

Conical Log Spiral Antennas

0.2~10GHz log periodic spiral antenna

This spiral antenna has a wide bandwidth, its outside circulation line provides excellent heat dissipation. Circular polarization can help to locate the radiation sources quickly. ideally suited for antenna measurement, far-field measurement, reflector feed, system integration, and other applications- Both left and righ hand circular polarization available.
