Abstract:
1. A single-layer antenna, comprising: a magnetic loop located on a plane and configured to generate a magnetic field, wherein the magnetic loop has a first inductive reactance adding to a total inductive reactance of the single-layer antenna; an electric field radiator located on the plane and within the magnetic loop, the electric field radiator coupled to the magnetic loop and configured to emit an electric field orthogonal to the magnetic field, wherein the electric field radiator has a first capacitive reactance adding to a total capacitive reactance of the single-layer antenna, wherein a physical arrangement between the electric field radiator and the magnetic loop results in a second capacitive reactance adding to the total capacitive reactance, and wherein the total inductive reactance substantially matches the total capacitive reactance; a transition formed on the magnetic loop, wherein a width of the transition is greater than a width of the magnetic loop; and a counterpoise formed on the magnetic loop and positioned substantially 180 degrees out of phase with the electric field radiator, wherein the transition is configured to substantially electrically isolate the counterpoise from the magnetic loop.
