Abstract : The important practical problems of evaluating the electromagnetic fields of finitesized antennas or of dipole arrays in a dissipative halfspace (freespace above an ocean or freespace above a plane earth) are investigated. In this report (1) expressions for the fields of horizontal coplanar dipole arrays in a dissipative halfspace are formulated, (2) integral expressions for the fields of horizontal linear antennas in a dissipative halfspace are formulated (which can be easily evaluated numerically), and (3) a useful 'travelingwave' insulated antenna immersed in a dissipative halfspace is examined.
