1. A golf ball comprising:

  • an array of flat-loop passive transponders constructed of electrically conductive material having respective planar inner and outer faces, wherein one passive transponder is arranged along each of three mutually perpendicular axes having a common point of intersection such that each passive transponder is equidistant from the point of intersection and each passive transponder is perpendicular to each of the other passive transponders to provide a substantially omni-directional radiation pattern;

    said transponders being configured with a discontinuous loop having confronting edges spaced apart to form a slot of predetermined gap;

    a layer of electrically insulating material disposed on one face of said loop;

    dielectric material disposed in said slot to cooperate in forming a capacitor, whereby the effective capacitive reactance may be controlled by the width of said gap and the choice of said dielectric material;

    a ball core disposed inside said transponder loops; and

    a cover covering said transponders.
