The behavior of a circular loop antenna near the interface between a conducting medium and air has been studied experimentally in terms of the following several parameters 1 circumference per wavelength betab of the loop, 2 loss tangent of the conducting medium, 3 depth of the loop below the interface, and 4 angle between the plane of the loop and the interface. The measured quantities were compared with the corresponding ones for a loop in a homogeneous dissipative medium of infinite extent wherever possible. Comparisons were made of the behavior of a loop when oriented both parallel to the interface and perpendicular to it in terms of such quantities as the driving-point admittance, the amplitude and phase distributions of the current, the effect of varying the distance from the interface, and the upward transmission of power into air from the loop when immersed in the conducting solution.
