New description: [New technical field] This is a charge sensing device and mobile communication device with charge sensing device, especially a charge sensing device that can use the original antenna of the mobile communication device as the sensing antenna. And the creation of a mobile communication device with a charge sensing device. • [Prior Art] With the advancement of technology, mobile communication devices have been widely used in everyday life, so users may be exposed to electromagnetic waves at any time. In order to prevent users from using mobile communication devices, the electromagnetic waves of mobile communication devices affect the human body. Therefore, today's mobile communication devices must pass the SAR (Specific Absorption Rate) test. In the prior art, it has been disclosed that the mobile communication device utilizes a charge sensing module to perform an embodiment for detecting the distance from the human body. In the prior art, the charge sensing module is electrically connected to a sensing antenna, and the proximity of the body is determined according to the change of the charge of the sensing antenna. When the human body approaches, the mobile communication device reduces the strength of the transmitted signal. However, if the prior art charge sensing module is used, there must be extra space inside the mobile communication device to configure the sensing antenna. For today's mobile communication devices that require light and short, the internals of the mobile communication device must be more complicated. Circuit layout, as a result, adds a lot of manufacturing costs. In view of this, it is necessary to create a new charge sensing device and its 3 M408882 mobile communication device with charge sensing device to solve the lack of prior art. [New Content] The main purpose of this creation is to provide a charge sensing device that has the function of making an antenna using the antenna of the mobile communication device. Another object of the present invention is to provide a mobile communication device having the above-described charge sensing device. To achieve the above objectives, the charge sensing device of the present invention is used for a mobile communication device. The mobile communication device has a processing module and a power amplifier. The charge sensing device includes an antenna, a sensing module, and a shutoff module. The antenna is used to transmit wireless communication signals required by the mobile communication device and to transmit wireless communication signals to the power amplifier. The sensing module is electrically connected to the antenna for sensing a charge change signal of the antenna, and transmitting the sensing signal to the processing module according to the charge change signal. The intercepting module is electrically connected to the antenna, the sensing module and the power amplifier to block signal interference between the antenna, the sensing module and the power amplifier. The mobile communication device with the charge sensing device of the present invention includes a processing module, a power amplifier and a charge sensing device. The power amplifier is electrically connected to the processing module. The charge sensing device is electrically connected to the power amplifier. The charge sensing device includes an antenna, a sensing module, and a shutoff module. The antenna is used to transmit the wireless communication signals required by the mobile communication device and to transmit the wireless communication signals to the power amplifier. The sensing module is electrically connected to the antenna for sensing a charge change signal of the antenna, and transmitting the sensing signal to the processing module according to the charge change signal. The processing module is configured to detect whether an object is close to or according to the sensing signal. keep away. The intercepting module is electrically connected to the antenna, the sensing module and the power M408882. The ribs block the signal interference between the antenna, the sensing module and the power amplifier. Due to the novel construction of this creation, it can provide industrial use, and it has improved efficiency. Therefore, it applies for a new type of patent according to law. s [Embodiment] The above and other objects, features and advantages of the present invention will become more apparent from the following description. In the following, please refer to FIG. 1 for the purpose of the charge sensing device of one embodiment of the present invention. In one embodiment of the present invention, the charge sensing device 1 can be applied to the mobile communication device 1 to detect whether the object is approaching or moving away by detecting the change of the charge, for example, detecting whether the human body is close to the mobile communication device. The mobile communication device 1 can be a mobile phone, a personal digital assistant (PDA), a notebook computer or a tablet computer, but the present invention is not limited thereto. It should be noted that the present invention does not limit the charge sensing device 10 to only the mobile communication device, and the charge sensing device 1 can also be applied to any device having an antenna module. The mobile communication device 1 includes a processing module 20, a power amplifier 30, and other application modules (not shown) in addition to the charge sensing device. The processing module 20 is electrically connected to the charge sensing device 1 and the power amplifier, and is formed by using a hardware with a hardware architecture or a hardware and hardware architecture. The processing module 20 is configured to control the functions of the remaining application modules 5 M408882 in the mobile communication device i for the user to perform functions such as calling or transmitting data. Since the function of using the mobile communication device 1 to talk or transfer data is not the most important purpose of the present creation, the operation mode of the processing module 20 will not be described herein. The power amplifier 30 is formed by a hard body or a firmware with a hardware structure, and is electrically connected to the antenna 11 for receiving or transmitting wireless communication signals. Power amplifier 30 linearly amplifies the power of the wireless communication signal as needed. The charge sensing device 10 includes an antenna 11, a sensing module 12, and a shut-off module 13. The antenna 11 can be a microwave antenna, but the creation is not limited thereto. The antenna 11 is used to transmit the wireless communication signals required by the mobile communication device 1, and transmits its wireless communication signals to the power amplifier 30 for subsequent processing. The antenna 11 can be adjusted in accordance with the transmission requirements of the mobile communication device 1, and the creation does not limit the specifications of the antenna 11. The sensing module 12 is constructed by using a circuit, a chip or a firmware in a hardware manner, and the present invention is not limited thereto. The sensing module 12 is electrically connected to the antenna 11 for detecting the charge change signal of the antenna 11 to know the electric charge exhibited by the antenna 11. As the object approaches or moves away from the antenna 11, the field shape of the antenna 11 changes simultaneously, further causing a change in the charge exhibited by the antenna 11. The sensing module 12 detects the charge change signal of the antenna 11, and includes detecting the magnitude of the charge of the antenna 11 and the changed voltage difference thereof to generate a sensing signal to the processing module 20. The processing module 20 knows whether an object is approaching or moving away from the mobile communication device 1 by the sensing signal, and can know the approximate distance between the object and the mobile communication device 1 for subsequent processing. For example, when the processing module 20 knows that the user is close to the mobile communication device 1, the processing module 20 can further control the screen of the flashing M408882 (not shown) of the mobile communication device 1, so that the user can operate the mobile communication device. 1. Alternatively, the processing module 20 can control the power amplifier 30 to reduce the transmission power of the wireless communication signal to reduce the influence of electromagnetic waves on the human body. Since the subsequent processing by the processing module 20 is not the primary purpose of the present creation, the control method will not be described herein. However, the manner in which the sensing module 12 directly detects the charge change signal of the antenna 11 easily affects the wireless communication signal required for the antenna 11 to transmit the mobile communication device 1. Therefore, the sensing module 12, the antenna 11 and the power amplifier 30 must have φ. The shut-off module 13 blocks the signal interference of each other. For the detailed operation principle of the shut-off module 13, please refer to FIG. 2. FIG. 2 is a circuit diagram of a cut-off module of the charge sensing device of one embodiment of the present invention. It should be noted that the embodiment of FIG. 2 illustrates that the wireless communication signal is a high frequency signal, and the charge change signal is a low frequency signal. However, the signal of the creation is not limited to the frequency listed above. In one embodiment of the present invention, the shut-off module 13 includes a radio frequency blocking circuit 131 and a DC blocking circuit 132. The RF blocking circuit 131 includes a φth capacitor C1 and an inductor L. The first capacitor C1 and the inductor L are electrically connected to each other, and the first capacitor C1 is connected to the ground. At the same time, the inductor L is electrically connected to the antenna 11 and the sensing module 12. When the antenna 11 transmits a high frequency wireless communication signal, the inductor L is disconnected to block the transmission of the high frequency signal. The high frequency signal that is not cut off will be directly grounded due to the high frequency short circuit of the first capacitor C1. In this way, the RF blocking circuit 131 can block the high frequency signal between the antenna 11 and the sensing module 12, so that the wireless communication signal is not transmitted to the sensing module 12. The DC blocking circuit 132 has a second capacitor C2, and the second capacitor C2 is electrically connected to the antenna 11 and the power amplifier 30. Therefore, when the low frequency charge change signal of the antenna 11 flows through the second capacitor C2, the second capacitor C2 is disconnected to block the low frequency signal. In this way, the DC blocking circuit 132 allows the high frequency wireless communication signal to be transmitted between the power amplifier 30 and the antenna 11, but the low frequency charge change signal cannot be transmitted. Therefore, the sensing module 12 detects only the charge change signal of the antenna 11 by the intercepting module 13, and does not detect the error due to receiving the high frequency wireless communication signal, and the sensing module 12 does not affect the module. To the characteristics of the antenna 11. It can be seen from the above description that, by the charge sensing device 10 of the present invention, the mobile communication device 1 can sense that the object approaches or moves away from the mobile communication device 1 without adding an additional sensing antenna, and does not affect the mobile communication device 1 Communication. Therefore, the mobile communication device 1 of the present invention can reduce the space of its internal circuit layout, which is obviously superior to the prior art mobile communication device. In summary, this creation, regardless of its purpose, means and efficacy, is showing its characteristics different from the well-known technology. You are kindly asked to review the examinations and give you a patent in advance, and you will feel the virtues. It is to be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the claims is intended to be limited by the scope of the application, and not limited to the above embodiments.
