Abstract
The terminal impedance of a full-wave dipole as a function of centre spacing has been measured for dipoles with the ratio of wave length to diameter (λ/D) equal to : 188, 94.3, 75.7, 62.9, 47.2, and 23.6 for centre spacings (S/λ)of .0212, .0423, .074, and .105. All measurements were made at 1000 megacycles using a standing wave measuring method with the half dipole above an image plane. The variation of resistance and reactance of the terminal impedance with centre spacing is shown in a series of graphs. A considerable increase in anti-resonant resistance and in antenna length for anti-resonance is observed to occur with increased gap length. The results are shown to agree well with existing literature.
