Download or read book An SBF Array for Reception of Atmospheric Noise written by J. A. Strom and published by . This book was released on 1974 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A four-element short-backfire array was designed, fabricated, and experimentally tested for use as a receiving antenna of low level atmospheric noise at 920 MHz. A complete set of design dimensions is presented as well as the resultant radiation patterns and frequency curves of sidelobe levels, half-power beamwidths, and input impedance. The effects of variations on the size and shape of the main reflector are discussed, especially when efficient operation with low sidelobes or high gain is of prime importance. Supporting data and tables of optimum design dimension are also provided for future VHF or UHF antenna applications in the gain range of 17 to 20 dB.
