Abstract :
Very little quantitative information is available on the behavior of an antenna over a nonplanar surface. A monopole over a metal hemisphere on a ground plane is a simple configuration which has possible applications to spacecraft antennas [1] and to broadcasting antennas erected on a hill. Measurements have been made of the driving-point admittance of a monopole with electrical lengths 
as a function of the radius 
of the hemisphere. A traveling-wave monopole with 
and 
was also investigated. The current distribution on the hemisphere was measured by means of a movable probe.
