Implantation and antenna orientation of an implantable sensor

A sensor system, comprising:

• a sensor including a sensor antenna having first coils, second coils, third coils, and fourth coils;
• and
• a transceiver including a transceiver antenna,
• wherein the first, second, third, and fourth coils of the sensor antenna are configured to couple with the transceiver antenna, the first coils are oriented in a first plane, the second coils are oriented in a second plane different than the first plane, the third coils that are oriented in a third plane different than the first and second planes, the second plane is at a first non-zero angle relative to the first plane, the third plane is at the first non-zero angle relative to the second plane, the third plane is at a second non-zero angle relative to the first plane, fourth coils that are oriented in a fourth plane different than the first, second, and third planes, the fourth plane is at the first non-zero angle relative to the third plane, the fourth plane is at the second non-zero angle relative to the second plane, and the first non-zero angle and the second non-zero angle are different non-zero angles;
• wherein the first non-zero angle is approximately 45 degrees, and the second non-zero angle is approximately 90 degrees.
