OG exemplary drawing
 
1. A glucose monitoring device configured to be worn on skin of a user, the glucose monitoring device comprising:
a mounting portion configured to support a printed circuit board, electronic circuitry, a first antenna, and a second antenna, wherein the electronic circuitry comprises a processor and a wireless communication module;
an adhesive layer configured to attach the mounting portion to the skin of the user; and
a glucose sensor configured to sense a glucose level in a bodily fluid of the user, the glucose sensor comprising:
a proximal portion configured to be coupled with the electronic circuitry; and
a distal portion including a tip portion configured to be positioned under the skin of the user,
wherein the glucose sensor is attached to the printed circuit board through a via of the mounting portion,
wherein the wireless communication module is configured to communicate data indicative of the glucose level to a portable handheld electronic device,
wherein the first antenna and the second antenna are electrically coupled with the electronic circuitry,
wherein the first antenna comprises a multi-loop antenna,
wherein the second antenna comprises a meandering antenna located on a same side of the printed circuit board as the electronic circuitry,
wherein the first antenna is configured to wirelessly communicate at a first frequency, and the second antenna is configured to wirelessly communicate at a second frequency different from the first frequency,
wherein at least one dielectric layer of the printed circuit board is disposed between a portion of the first antenna and a portion of the second antenna.
