Abstract

Techniques for implementing antenna configurations with substantially co-located axes are disclosed. A method for constructing co-located antennas includes winding a first antenna on a support, the first antenna having a first magnetic dipole in a first orientation; and winding a second antenna on the support through a first set of openings in the support, the second antenna having a second magnetic dipole in a second orientation, wherein the first orientation is different from the second orientation, and wherein a center of the first magnetic dipole substantially co-locates with a center of the second magnetic dipole.

Claims

1. A method for constructing co-located antennas, comprising:

winding a first antenna on a support, the first antenna having a first magnetic dipole in a first orientation; and

winding a second antenna on the support through a first set of openings in the support, the second antenna having a second magnetic dipole in a second orientation, wherein the first orientation is different from the second orientation, and wherein a center of the first magnetic dipole substantially co-locates with a center of the second magnetic dipole.

2. The method of claim 1, further comprising placing a first insulator between the first antenna and the second antenna.

3. The method of claim 1, wherein the first orientation is orthogonal to the second orientation.

4. The method of claim 1, further comprising winding a third antenna on the support through a second set of openings in the support, the third antenna having a third magnetic dipole in a third orientation, wherein the third orientation is different from the first orientation and the second orientation, and wherein a center of the third magnetic dipole substantially co-locates with the center of the first magnetic dipole and the center of the second magnetic dipole.

5. The method of claim 4, wherein the first orientation, the second orientation, and the third orientation are mutually orthogonal.

6. The method of claim 4, further comprising placing a first insulator between the first antenna and the second antenna.

7. The method of claim 6, further comprising placing a second insulator between the second antenna and the third antenna.
