An antenna is provided having a plurality of turns of electrical conduction path around a ferrite core, wherein the plurality of turns comprise traces on printed circuit boards on two sides of the ferrite core. Further, the antenna may include a first circuit board having a plurality of electrical traces spanning the first circuit board substantially parallel to its width, a second circuit board having a plurality of electrical traces spanning the second circuit board at an angle relative to its width and an intermediate board having a central opening. The first and second circuit boards are in a stacked configuration, having ferrite material therebetween within the central opening. The electrical traces on the first and second circuit boards are electrically coupled, forming a plurality of turns of electrical conduction path around the ferrite material, and to thereby form, at least in part, the antenna. |
