Abstract:
1. A three-axis antenna comprising: a cross-shaped core having a pair of X-axis arms projecting in an X-axis direction and a pair of Y-axis arms projecting in a Y-axis direction orthogonal to the X-axis direction in an orthogonal coordinate system, the X-axis arms comprising head sections, and the Y-axis arms comprising head sections; X-axis winding wire wound about the X-axis arms; Y-axis winding wire wound about the Y-axis arms; and Z-axis winding wire enclosing the cross-shaped core outside the head sections of the X-axis arms and the head sections of the Y-axis arms, wherein each of the X-axis winding wire, Y-axis winding wire, and Z-axis winding wire has a winding origin and a winding terminus; each winding origin and each winding terminus of the X-axis winding wire, the Y-axis winding wire, and the Z-axis winding wire is electrically connected to a respective terminal; and center taps of the X-axis winding wire and the Y-axis winding wire are electrically connected to respective terminals for a total of eight terminals, and wherein the Z-axis winding wire is housed so as to cover surfaces of the head sections of the X-axis arms and of the Y-axis arms of the cross-shaped core.
