Description

Cavity Backed Spiral Antenna

2GHz to 6GHz

OBS-2060

The OBS-2060 is a compact, moderate gain, moderate VSWR, circularly-polarized cavity-backed spiral antenna designed to transmit and receive in the frequency band of 2.0 GHz to 6.0 GHz. The antenna exhibits an excellent impedance match and radiation pattern.

It is capable of receiving both linearly polarized signals and circularly polarized signals. The linear gain (dBil) is about 3 dB lower than the circular gain (dBic).

The antenna has the advantages of a low profile, a planar aperture, no phase center offset, near-constant beam width across the frequency band, symmetrical radiation beam width, extreme flexibility for carrying, and lightweight.

These advantages make the antenna a very good candidate for electronic warfare, direction finding, telemetry, and surveillance systems, as well as flush-mounted airborne applications. The antenna can also be used as a broadband feed for reflector antennas.

The antenna’s outer dimensions are a diameter of 68mm and a height of 50mm.
