Equations of deviation of geodesic lines, describing relative oscillations of two free particles, was obtained earlier by Synge [17].
The mathematical model for such an antenna consists of two free test-particles moving on neighbouring geodesic lines located infinitely close to one another.
For two neighbour geodesic lines, the following relation is obviously true
