Abstract
There are provided PCB capacitor variable device and method. The PCB capacitor variable device includes: a PCB forming any parallel capacitor by disposing a dielectric layer between a first pattern and a second pattern; and a switch unit connected to a pattern of one of the capacitors to switch the pattern of one of the capacitors so as to control equivalent capacitance of the capacitor. According an exemplary embodiment of the present disclosure, the capacitor is implemented using the PCB pattern and the dielectric substance and therefore the miniaturization and weight lightening of the wireless communication system may be implemented. Further, according to an exemplary embodiment of the present disclosure, the capacitor may be selectively switched and therefore the optimized frequency required in the output of the amplification unit may be implemented.
