Abstract : A study is presented of the radiation properties of a trailing wire antenna. The antenna is assumed to be a thin center-fed dipole antenna that is either straight making an angle with the vertical or curved in the shape of a catenary. First an expression is derived for the equivalent horizontal and vertical dipole moments of the trailing wire antenna from which the far fields can be computed by standard methods. The equivalent dipole moments are obtained because they are useful in mode theory. Second the far fields are calculated directly, no assumptions being made except those necessary to evaluate the integrals in closed form. The far field patterns obtained in this way are useful in ray tracing. For electrically short antennas both methods should lead to the same far field patterns. (Author)
