BACKFIRE ANTENNAS FOR SHF, UHF, AND VHF BANDS,

Abstract

The application of the backfire principle to endfire antennas increases their gain by 4 to 6 db over that of the original gain-maximized array. Basic investigations are described on a 9080-Mc backfire antenna which was converted from an optimized Yagi antenna. Backfire antenna models have been successfully tested at frequencies of 3000, 600, and 220 Mc. The design procedure and physical dimensions are given for all models. A method for building backfire antennas with gain figures up to 25 db is discussed.
