1. A signal processing device comprising a target apparatus and a feeding apparatus, wherein the feeding apparatus comprises:
a first conductor configured to transmit a radio frequency signal;
an insulating medium covering the first conductor; and
a second conductor covering the insulating medium;
wherein a first portion of the insulating medium is covered by the second conductor and a second portion of the insulating medium extends beyond a first end of the second conductor,
wherein a first portion of the first conductor is covered by both the second conductor and the insulating medium, a second portion of the first conductor extends beyond the first end of the second conductor and is covered by the insulating medium, and a third portion of the first conductor extends beyond a first end of the insulating medium, and
wherein the third portion of the first conductor is configured to be connected to the target apparatus to feed the radio frequency signal to the target apparatus and is configured to form a capacitive impedance with the target apparatus, the second portion of the first conductor is configured to form an inductive impedance with the target apparatus, and an absolute value of a sum of the capacitive impedance and the inductive impedance is less than or equal to a preset impedance threshold.
