Encapsulated multi-band monopole antenna

An antenna comprising:

• a substrate having a first surface and a second surface;
• a plurality of channels within the substrate;
• a first set of monopole elements, each of the monopole elements of the first set made of a first conductive material and extending within one of the plurality of channels, the monopole elements of the first set are rotationally aligned around an imaginary axis of the substrate passing from the second surface to the first surface;
• a second set of monopole elements, each of the monopole elements of the second set made of a second conductive material and extending within one of the plurality of channels, the monopole elements of the second set are rotationally aligned around the imaginary axis of the substrate passing from the second surface to the first surface;
• a first conductive path connecting a first monopole element of the first set of monopole elements with a first monopole element of the second set of monopole elements;
• a second conductive path connecting a second monopole element of the first set of monopole elements with a second monopole element of the second set of monopole elements, wherein the antenna is resonant at a first frequency and resonant at a second frequency;
• and
• a conductive ring disposed along an outside of the substrate, the conductive ring creating capacitive coupling with the first and second conductive paths.
