DEVICE WHICH SHOWS FEATURES OF LINEAR ANTENNAS Russian patent published in 1997 - IPC

FIELD: education. SUBSTANCE: device has emitter which is designed as serial circuit of high-frequency oscillator, rectangular funnel, electromagnetic lens, unit which alters masks, alternating masks, rotating rack and analyzing unit which has receiving funnel, detector and indicator. Said serial circuit is located base. Each alternating mask is designed as metal plate with hole which size and shape are determined by type of amplitude distribution to be modeled and electric size of antenna to be modeled. In addition it has dielectric strap which is designed as cylindrical prism which generatrix is determined by phase distribution to be modeled. EFFECT: possibility to model and demonstrate influence of aperture size, amplitude-phase distribution on beam pattern of continuous linear antenna. 3 dwg, 1 tbl
