Helios deployable antenna


The Helios Deployable Antenna can be customized to operate from 400Mhz to 3000Mhz. The HCT Helios series of antennas can accommodate several operational purposes from near hemispherical coverage to narrow beam-widths, including ISO-FLUX beam patterns. The Helios antenna has been created with a memory shaped alloy deployment, bringing reliability to space-based deployments and eliminating the need for burn wire and other mechanical deployment methods.
Antenna patterns can be arranged to be either right hand or left hand circularly polarized. Thus, having significant advantages over linearly polarized antennas. The antennas can be developed to reside in less than one-half of a 1U Cube structure. This makes the innovative Helios Antenna appropriate for small satellite applications.
