The fields of a dipole source located over a variable impedance surface are considered. A method of obtaining solutions of the integral equation for the tangential field is outlined. Numerical results are given for the resulting radiation patterns for an exponentially tapered variation of the surface impedance. It is shown that the tapering has the advantage of reducing the lobe structure of the low‐angle radiation.
