Description of the Invention: [Technical Field] The present invention relates to an antenna frequency offset compensation device, and more particularly to a method for compensating for a frequency offset of a wireless communication device due to human body contact by a tuning matching circuit Device. [Prior Art] In recent years, with the rapid development of communication technologies, wireless communication devices such as mobile phones have become an indispensable part of communication between people in modern life with high mobility advantages. In order to meet the high communication quality requirements, the antenna 101 signal receiving strength of the wireless communication device 10 must be maintained above a certain level in order to balance the high performance characteristics. However, the human body is a good conductor of electromagnetic waves, so when the user holds the wireless communication device 1G, the human body will record the electromagnetic waves and rely on the energy to enter the human body, so that the antenna im receiving and the Wei intensity of the field rail device 1G are both reduced. The range of reception is reduced and the signal is distorted, and the wireless communication device generates higher noise to affect the quality of the track. In order to solve the problem of the quality of the human body, the wireless communication device is usually compensated by increasing the transmission power or by connecting the parasitic resonance element to the circuit substrate 102 of the wireless communication device 10 as shown in FIG. However, the method of increasing the transmission power reduces the battery life of the wireless communication device 10 and the electromagnetic absorption rate of the skin; the value of the skin is increased, and the value of the e is increased. The frequency offset can not be accurately compensated, so that the compensation benefit is not good. SUMMARY OF THE INVENTION In view of the above, the present invention is to solve the problem that the antenna 200931821 material compensation device is adjusted by the day-rate offset compensation device. The spectrum matching circuit compensates for the situation that the wireless communication device causes the reception quality to be degraded due to the influence of human body contact. • The problem of the above-mentioned problem is solved by riding the problem. The solution proposed by the current performance is: •==line component, plural (4) matching circuit and sensing city module, group = day = money shift compensation device for wireless communication device frequency offset compensation antenna frequency offset compensation device antenna element side device receiving / transmitting radio signal. antenna frequency offset Compensating device == consists of an inductive component or a capacitive component or a combination of the two, the phase of the line produces no frequency offset caused by the influence of the human antenna The antenna frequency offset compensation device f should switch the module to perform the antenna frequency offset compensation device==. The antenna frequency offset compensation device of the present invention, when the human body is not connected: the cover sensing area, the antenna frequency offset compensation Device system=day: the first of the frequency offset compensation device—the tuning matching circuit is electrically connected to the outer cover sensing area of the device; the communication module performs the switching of the switching dynamic offset and the antenna frequency offset compensation device The second tuning matching circuit switched to the antenna frequency offset compensating device is electrically connected to the antenna component to receive/transmit the radio signal, so that the antenna frequency offset compensation is performed. The component is not affected by human contact, and the shift: ::: The receiving quality of the wireless communication device. Among them, the day = = ^ = _ riding TM road TM various frequency 6 200931821 The antenna frequency offset compensation device of the invention can be switched by the antenna frequency offset compensation device The matching circuit is electrically connected to the antenna element, so that the wireless communication device does not cause signal attenuation-subtraction due to human contact, so that the wireless communication device can be maintained optimally.实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施方块 Block diagram of an embodiment of the apparatus, FIG. 3 is a schematic diagram of an embodiment of an antenna frequency offset compensation apparatus according to the present invention. As shown in FIG. 2, the antenna frequency offset compensation apparatus is applied to a mobile phone or a personal digital assistant mobile phone (PDA ph〇ne For example, the wireless communication device 30 is configured by setting two sets of tuning matching circuits. The antenna frequency offset compensating device 20 is mainly composed of an antenna element 2, a first tuning matching circuit 2, a second tuning matching circuit 203, and an inductive switching. The module 204 is composed of an antenna element 2() 1 of the antenna frequency offset compensating device 20 for receiving/transmitting the radio signal of the wireless condition device 30. The antenna frequency offset compensating device 2 ❹ the second tuning matching circuit 202 or the second tuning matching circuit 203 of the antenna frequency offset compensating device 2 is composed of at least one inductive component or at least one capacitive component or both Composed in combination to cause the antenna elements to produce different frequency offsets. The inductive switching module 2〇4 of the antenna frequency offset compensating device 20 performs the antenna frequency offset compensating device 2 when the external sensing device 3〇1 of the wireless communication device 30 senses that the human body contacts the wireless communication device 30. The switching of the tuning matching circuit compensates for the frequency offset caused by the antenna element 201 of the antenna frequency offset compensating device 20 being affected by the human body contact, causing the antenna frequency 200931821, and the antenna element 201 of the half offset compensating device 20 to change its performance. The situation in which the wireless communication device 30 receives the quality is reduced. The tuning matching circuit of the antenna frequency offset compensating device 20 can be increased according to actual use requirements to compensate for various frequency offset situations. When the human body is not in contact with the cover sensing area 301 of the wireless communication device 30, the wireless communication device 30 is electrically connected to the antenna element 201 by the first tuning matching circuit 202 of the antenna frequency offset compensation device 20, and receives/transmits the wireless communication device. 30 radio signals. However, when the human body contacts the wireless communication device U 30 to cover the sensing area 301, the sensing switching module 204 of the antenna frequency offset compensation device 20 performs a switching operation to switch the antenna frequency offset compensation device 20 to the second. The tuning matching circuit 203 is electrically connected to the antenna element 201 to receive/transmit the radio signal of the wireless communication device 30. The antenna element 201 of the antenna frequency offset compensating device 20 is not affected by human body contact, and the antenna element 201 of the antenna frequency offset compensating device 20 is affected to receive/transmit radio signals. In summary, the human body is a lossy medium to the wireless communication device 30. Therefore, the wireless communication device 30 often changes the antenna performance due to the human body contact relationship, resulting in a decrease in the reception quality of the wireless communication device 30. The antenna frequency offset compensation device 20 of the present invention can instantly compensate the human body for contacting the wireless communication device 30, so that the wireless communication device 30 generates signal attenuation, so that the wireless communication device 30 can maintain the optimal performance. While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the equivalent of the modification and retouching of the present invention is still within the spirit and scope of the present invention. This issue 8 200931821 - within the scope of the search for protection.
