AN ACTIVE RETRODIRECTIVE ARRAY WITH BILATERAL TUNNEL DIODE AMPLIFIERS.

Abstract

The array factor of a 21-element retrodirective array, with bidirectional amplifiers integrated into the interconnecting transmission lines, is derived in this report. The directivity of the array for boresight and off-angle illumination is calculated for various array spacings. Basic array measurements were taken on a 4-element S-band array. The constructed array consisted of equiangular spiral antennas, balanced strip transmission lines and bilateral tunnel diode amplifiers. Theoretical gain expressions for the amplifiers are derived and measured gain vs. frequency curves plotted. (Author)
