An amplifier is built into the main board 4 disposed on the upper surface of the lower cover 3. A micro antenna 5 is provided in the case 3 in close proximity to the upper part of the main board 4, and a second signal generator is installed in the part protruding from the casing that connects and supports the micro antenna 5. A circuit board 6 is connected. The signal generator on the second circuit board 6 is a circuit that generates the same signal as the signal amplified by the amplifier on the main board 4.

In this way, the effect is extremely large for things that require minute design, such as high-frequency circuits.
