Abstract

The invention discloses a wireless communication apparatus and method. The wireless communication apparatus may include: an oscillator including a coil assembly exposed to an outside of the wireless communication apparatus, a variable capacitor, and a negative resistor; and a phase locking circuit connected to the coil assembly and the negative resistor. The phase locking circuit may be configuredto 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.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2018-0131853 and Korean Patent Application No. 10-2019-0079465 filed with the Korean Intellectual Property Office on October 31, 2018 and July 2, 2019, respectively, so The entire disclosure of the aforementioned Korean Patent Application is hereby incorporated by reference for all purposes. technical field [0002] The following description refers to wireless communication technologies.
