Abstract
On the basis of the derived far field of a turnstile antenna rotating about an arbitrary axis, the signal observed at the terminals of a pair of mutually orthogonal receiving dipoles is evaluated. The phase and amplitude of the signals received by a single dipole at two mutually orthogonal orientations and a circularly polarized antenna are determined as special cases. The results indicate that phase discontinuities which might possibly degrade the performance of a phase sensitive receiver may occur if the turnstile rotates about one of its dipoles, assuming a linearly polarized receiving antenna. This is not observed if a circularly polarized receiving antenna is used.
