Abstract:
1. A single-sided multi-band antenna, comprising: a magnetic loop located on a plane and configured to generate a magnetic field, the magnetic loop including at least a first section and a second section, wherein the magnetic loop has a first inductive reactance adding to a total inductive reactance of the multi-band antenna; a monopole formed by a substantially stair-shaped bend of the magnetic loop, the monopole configured to create a resonant mode of a first frequency band; and 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 at a second frequency band orthogonal to the magnetic field, wherein the electric field radiator has a first capacitive reactance adding to a total capacitive reactance of the multi-band 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.
