Abstract :

It is the object of this investigation to measure the driving-point admittance, the amplitude distribution of the current, and the phase distribution of the current, relative to the phase at the driving-point for a dipole antenna immersed in a homogeneous conducting medium. Measurements of the driving-point admittance have been made for a range of values of the ratio $\\sigma /\\omega \\epsilon_{r}\\epsilon_{0}$ of the medium taking the electrical height of the antenna $\\beta h$ as a parameter. The ratio $\\sigma /\\omega \\epsilon_{r}\\epsilon_{0}$ is varied from $\\sigma /\\omega \\epsilon_{r}\\epsilon_{0}=0.036$ to $\\sigma /\\omega \\epsilon_{r} \\epsilon_{0}=8.8$ and the antenna height $\\beta h$ is varied from $\\beta h=0.1$ to $2\\pi$ at intervals of 0.1. The amplitude and phase distributions of the current have been measured for $\\beta h = \\pi/2, 3\\pi/4, \\pi$ , and $5/4\\pi$ in a homogeneous conducting medium whose conductivity is varied from $\\sigma /\\omega \\epsilon_{r} \\epsilon_{0}=0.036$ to $\\sigma /\\omega \\epsilon_{r}\\epsilon_{0}=8.8$ .
