摘要： A variable capacitor, including: two movable plates, two poles, and one rotary shaft. The two movable plates are conductor belts, and the conductor belts are sheathed in insulators. The two poles are conductors, and each is capable of rotating around an axis thereof. First ends of the two movable plates are connected via the insulators and fixed on the rotary shaft, and second ends of the two movable plates are connected to the two poles, respectively. A conductor member of the two movable plates directly contacts the two poles. The lengths of the two movable plates are identical, and are greater than the distance from one pole to the rotary shaft.
