Description of the invention () This creation provides an antenna switching device, especially an antenna switching device installed in a radio handset. The main advantage of radio mobile phones, such as mobile phones, is that they can be carried and used everywhere. When using a radio phone in a car, in order to save the battery of the phone and increase the efficiency of radio transmission and reception, a car dock is usually set up in the car to supplement the power of the phone and connect the phone to a highly efficient car antenna. Therefore, mobile phone manufacturers usually install an antenna switching device inside the mobile phone to switch the mobile phone antenna or the car antenna. Figures 1 and 2 show two conventional mobile phone antenna switching devices. Please refer to Figure 1. FIG. 1 shows a schematic diagram of an antenna switching device of a conventional radio handset 10. FIG. The mobile phone 10 includes a housing 12, a radio frequency module 14 is disposed in the upper end of the housing 12, a mobile phone antenna 20 is disposed in the upper end of the housing 12, and a connection port 18 is disposed in the lower end of the housing 12 for connecting the car antenna 22 Socket 24 to enable the RF module 14 to be connected to the car antenna 22. The port 18 includes a mechanical or electronic switch (not shown) for switching the connection between the RF module 14 and the mobile phone antenna 20 or the car antenna 22. The mobile phone 10 further includes a transmission line 26 for connecting the RF module 14 and the port 18 and another transmission line 28 for connecting the port 18 and the mobile antenna 20. When the user inserts the socket 24 of the car antenna 22 into the port 10 of the mobile phone 10, the toggle switch in the port 18 will be actuated to make the transmission line 2 This paper standard applies to China National Standards (CNS) A4 specification (210X297 ) (Please read the precautions on the back before filling in this page).

Description of invention () 26 Can be connected to the car antenna 22 At this time, the mobile phone 10 can use the highly efficient car antenna 22 to receive or transmit radio signals. When the user separates the mobile phone 10 from the socket 24 of the car antenna 22, the toggle switch in the port 18 connects the transmission line 26 to the transmission line 28 to use the mobile phone antenna 20 to receive or transmit radio signals. The disadvantage of the antenna switching device of the mobile phone 10 is that when the mobile phone antenna 20 is used to receive or transmit radio signals, the RF module 14 passes the first transmission line 26 'port 18 and the second transmission line 28 to transmit the signal to the mobile phone antenna 20. _This long signal transmission path will cause great loss to the received or transmitted signal. Please refer to Figure 2. FIG. 2 shows a schematic diagram of another antenna switching device of the conventional radio handset 30. FIG. The mobile phone 30 includes a housing 32, a radio frequency module 34 is disposed in the upper end of the housing 32, a mobile phone antenna 38 is disposed in the upper end of the housing 32, and a connection port 40 is disposed in the upper end of the housing 12 for connecting to the car The antenna 42 enables the RF module 34 to be connected to the car antenna 42. The car antenna 42 includes a socket 36 that can be connected to the bottom end of the mobile phone 30 to provide power, and a plug 44 connected to the socket 36 via the transmission cable 50 for connecting to the port 40. The port 40 includes a switch for switching the connection between the radio frequency module 34 and the mobile phone antenna 38 or the car antenna 42. The mobile phone 30 further includes a transmission line 46 for connecting the RF module 34 and the port 40 and another transmission line 48 for connecting the port 40 and the mobile phone antenna 38 »When the user inserts the plug 44 of the car antenna 42 into the mobile phone 30 The standard of this paper is the National Standard Falcon (CNS) A4 specification (2 丨 〇297) (please read the note Ϋ on the back and then fill out this page) — Pack. Order the consumption of employees of the Central Bureau of Standards of the Ministry of Economic Affairs Cooperative Duprinting 317067 A7 B7__ V. Description of invention () When port 40 is used, the toggle switch in port 40 will be actuated to enable radio frequency module 34 to be connected to car antenna 42 and mobile phone 30 can be used High-efficiency car antenna 42 to receive or transmit radio signals. When the user separates the mobile phone 30 from the plug 44 of the car antenna 42, the toggle switch in the port 40 connects the Fu transmission line 46 to the transmission line 48 to use the mobile phone The antenna 38 can receive or transmit radio signals. The antenna switching device of the mobile phone 40 can greatly shorten the transmission path between the radio frequency module 34 and the mobile phone antenna 38 to reduce the signal loss. However, the socket 36 An additional plug 44 has to be added to connect. Port 40. After the user connects the socket 36 of the car antenna 42 to the bottom end of the mobile phone 30, the plug 44 connected to the socket 36 needs to be inserted into the mobile phone 3 again. The port 40 of this kind is very cumbersome and makes the structure of the socket 36 quite complicated, which is quite inconvenient for the user. Therefore, the main purpose of this creation is to overcome the limitations of the aforementioned conventional technology and provide a The antenna switching device of a radio handset solves the problems encountered above.

When the socket 24 of the car antenna 22 is not inserted into the three-wire socket 68, the connectors 74 and 76 are electrically connected to each other so that the voltage source Vs can be electrically connected to the electronic switch 67 through the blocking inductor 82 and the signal line 70. When the electronic switch 67 senses the presence of the voltage source Vs, it will turn on the transmission lines 90 and 92 to enable the radio frequency module 66 to receive or transmit radio signals via the mobile phone antenna 64. When the socket 24 of the car antenna 22 is inserted into the three-wire socket 74, the connectors 74 and 76 are forced to be disconnected to cut off the connection between the voltage source Vs and the electronic switch 67. When the electronic switch 67 senses that the voltage source Vs has disappeared, it will turn on the transmission lines 94 and 92 to enable the RF module 66 to receive or transmit radio signals through the highly efficient automotive antenna 22. The Ministry of Economic Affairs, Central Standard, and Beigong Coupling Capacitor 80 is used to prevent the voltage source Vs from being directly input into the RF module 66 to avoid unpredictable effects on the RF module 66 and allow high-frequency radio signals to pass through. The blocking inductor 82 is used to prevent the high-frequency wireless signals from going back to the electronic switch 67 to form an unstable feedback loop, and to pass the voltage source Vs to control the electronic switch 67. 317067 A7 B7 V. Description of the invention () When comparing the mobile phone 60 with the mobile phone 10 shown in FIG. 1, it can be found that when the mobile phone 60 uses the mobile phone antenna 64 to receive or transmit radio signals, its signal transmission path is much higher than that of the mobile phone. 10 is short, so it can greatly reduce the loss of wireless signals in the transmission path.
