| ID No : | 52 Edit | Title: | An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy |
| Summary / Review : |
Radio telescope in orbital space. From the author's abstract: "Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited metal dipole arrays meet these three requirements. In the proposed design, dipole antenna elements are equally spaced on a Kevlar spherical balloon. Beam steering is accomplished with a combination of switches and phase shifters. The beam can be moved to any position on the sky with no significant change in the shape of the main beam. The half-power beamwidth and the sidelobe level are 20 degrees and -18 dB, respectively at 26 MHz. The characteristics of the inflatable antenna are well matched to the needs of a low-frequencyorbiting radio telescope." - MP
