An integral expression is derived for the current distribution on an infinite, perfectly conducting antenna alined with the magnetic field in an anisotropic incompressible plasma. Use is made of the Wilcox radiation condition and the notion of generalized eigenfunctions. An asymptotic evaluation of the integral is presented, and it is shown that the current distribution contains the wave numbers of the two plane waves possible in this medium.
