OG exemplary drawing
 
1. A glucose monitoring device configured to be worn on skin of a user, the glucose monitoring device comprising:
a mounting surface configured to support a transmitter 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 surface 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 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 that is disposed in at least one layer of the transmitter circuit board,
wherein the second antenna comprises a meandering antenna that is located above the first antenna on a same side of the transmitter 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.
