1. A surgical instrument, comprising:
a shaft;
an articulation joint extending distally from the shaft;
an end effector extending distally from the articulation joint, wherein the end effector is configured to grasp tissue, and wherein the end effector comprises:
a jaw; and
a staple cartridge seatable in the jaw, wherein the staple cartridge comprises:
a cartridge body;
staples removably stored in the cartridge body; and
a first antenna attached to the cartridge body; and
a remote power source configured to supply power;
a second antenna configured to cooperate with the first antenna when the staple cartridge is seated in the jaw to transmit at least one of the power and a data signal to the staple cartridge; and
a tuning electronics package located in a cavity in a proximal portion of the end effector, wherein the cavity is proximal to the second antenna and distal to the shaft, and wherein the tuning electronics package is configured to facilitate a locally tunable wireless transmission of the at least one of the power and the data signal, wherein the tuning electronics package comprises a processor and a memory storing program instructions, which when executed by the processor, cause the processor to implement an adjustment of a rate of the wireless transmission of the power.
