1. A wireless communication apparatus, comprising:
an oscillator comprising
a coil assembly, comprising a plurality of coils, exposed to an outside of the wireless communication apparatus,
a variable capacitor, and
a negative resistor;
a phase locking circuit connected to the coil assembly and the negative resistor, and configured to generate a control signal to lock an oscillation frequency of the oscillator based on an oscillation signal generated by the oscillator, and provide the generated control signal to the variable capacitor;
a housing configured to accommodate the phase locking circuit and support the coil assembly protruding toward the outside of the wireless communication apparatus; and
a phase controller configured to supply the plurality of coils with respective powers designated based on a target bandwidth, in order to communicate through the target bandwidth among a plurality of bandwidths defined based on a number of the plurality of coils.
