Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a structural diagram of an antenna detection circuit provided in an embodiment of the present invention, as shown in fig. 1, including at least two radio frequency sub-circuits and a first resistor R1, where each radio frequency sub-circuit includes a test socket 1 and an inductor L; the first end of the inductor L is connected with the first end of the test socket 1, and the second end of the inductor L is grounded; the first end of the test socket 1 is connected with the radio frequency conduction end, and the grounding end of the test socket 1 is grounded; the detection ends of the test socket 1 of different radio frequency sub-circuits are all connected with a power supply, the detection ends of the test socket 1 of different radio frequency sub-circuits are also all connected with a first end of the first resistor R1, and a second end of the first resistor R1 is connected with a level detection unit; under the condition that a test wire connected with an antenna 2 to be tested is not inserted into the test socket 1, the detection end of the test socket 1 is disconnected with the grounding end; when a test wire connected to the antenna 2 to be tested is inserted into the test socket 1, the detection end of the test socket 1 is electrically connected to the ground.
In this embodiment, the level detection unit is configured to perform level detection, and the power supplies connected to the different rf sub-circuits are the same power supply. Considering the actual test situation of the electronic device, as long as one radio frequency sub-circuit is in the conduction test state, the electronic device cannot perform the coupling test. Once more than one radio frequency sub-circuit is detected to be in the conduction test state, other radio frequency sub-circuits do not need to be judged, and the adjustment operation of the state of the electronic equipment does not need to be carried out.
In this embodiment, when a test wire connected to the antenna 2 to be tested is not inserted into the test socket 1, the detection end of the test socket 1 is disconnected from the ground end; when a test wire connected to the antenna 2 to be tested is inserted into the test socket 1, the detection end of the test socket 1 is electrically connected to the ground. For better understanding of the test socket 1, please refer to fig. 2, and fig. 2 is a structural diagram of the test socket according to an embodiment of the present invention.
As shown in fig. 2, 21 denotes the detection terminal of the test socket 1, and 22 denotes the ground terminal of the test socket 1, and when no test line is inserted, the coupling test state detection terminal is not grounded. Under the conduction test state, the test socket 1 is inserted into the test wire, the buckling groove of the test wire is buckled on the two separated parts of the buckling ring at the same time, the two separated parts of the buckling ring are connected together again through the buckling groove of the test wire, and at the moment, the detection end is connected with the grounding end through the buckling ring, namely, the detection end is connected to the ground.
In this embodiment, the detection terminal of the antenna detection circuit is connected to the detection terminal of the improved test socket 1. The test terminals of the plurality of test sockets 1 are connected together and then gathered to one main chip test port (level detection IC output). In fig. 1, the rf sub-circuit located above may be the rf sub-circuit 01, and the rf sub-circuit located below may be the rf sub-circuit 02, and the new design changes the judgment logic of the detection circuit, which is opposite to the judgment logic of the original detection circuit (i.e. the low level is a conduction test state, and the high level is a coupling test state), specifically as follows:
the first radio frequency sub-circuit 01 and the radio frequency sub-circuit 02 are in a conduction test state, the two access test sockets 1 are inserted with test lines, the detection ends of the two test sockets 1 are grounded and are in a low level, and the second end of the first resistor R1 outputs the low level. And judging that the whole machine is in a conduction test state.
And secondly, only the radio frequency sub-circuit 01 is in a conduction test state, only the test socket 1 of the radio frequency sub-circuit 01 is inserted into a test line, and the detection end of the test socket 1 is grounded and is in a low level. The test socket 1 of the rf sub-circuit 02 is not inserted with a test line, and the detection end of the test socket 1 is suspended. Since the detection end of the test socket 1 of the rf sub-circuit 01 is connected to the detection end of the test socket 1 of the rf sub-circuit 02, the second end of the first resistor R1 still outputs a low level. And judging that the whole machine is in a conduction test state.
And thirdly, only the radio frequency sub-circuit 02 is in a conduction test state, only the test socket 1 of the radio frequency sub-circuit 02 is inserted with a test line, and the detection end of the test socket 1 is grounded and is in a low level. The test socket 1 of the radio frequency sub-circuit 01 is not inserted with a test wire, and the detection end of the test socket 1 is suspended. Since the detection end of the test socket 1 of the rf sub-circuit 02 is connected to the detection end of the test socket 1 of the rf sub-circuit 01, the second end of the first resistor R1 still outputs a low level. And judging that the whole machine is in a conduction test state.
Fourthly, the radio frequency sub-circuit 01 and the radio frequency sub-circuit 02 are in a coupling test state, no test line is inserted into the radio frequency sub-circuit 01 and the radio frequency sub-circuit 02, and the detection end of the test socket 1 of the radio frequency sub-circuit 01 and the detection end of the test socket 1 of the radio frequency sub-circuit 02 are both suspended and not grounded. As can be seen from the circuit design, both of the two detection terminals are at a high level, and the second terminal of the first resistor R1 outputs a high level. And judging that the whole machine is in a coupling radiation test state.
In this embodiment, the determination logic of the antenna detection circuit is changed, that is, when the terminal device designs a multi-channel multi-antenna, it is determined that the terminal device is in the conduction test state as long as more than one radio frequency channel is detected, and the state of the terminal device is not adjusted. The terminal state is adjusted only if all paths are in the coupled radiating state. The antenna detection circuit design can simplify the number of the main chip antenna detection ports to only one, thereby simplifying the detection process and saving the cost. The layout space of the circuit board is improved, and meanwhile the problem that the 5G multi-antenna design requires occupation of a chip detection port can be solved.
Optionally, the antenna detection circuit further includes a second resistor R2, and the detection ends of the test socket 1 of different rf sub-circuits are all connected to a power supply through the second resistor R2.
In this embodiment, please refer to fig. 3 for better understanding of the above-mentioned arrangement, and fig. 3 is a structural diagram of an antenna detection circuit according to an embodiment of the present invention. As shown in fig. 3, the antenna detection circuit further includes a second resistor R2, and the detection terminals of the test socket 1 of different rf sub-circuits are all connected to a power source through the second resistor R2. Thus, when the voltage of the power supply is relatively large, the second resistor R2 can protect the circuit.
Optionally, when a test line connected to the antenna to be tested is not inserted into the test socket, the first end of the test socket is in conduction with the test line; and under the condition that a test wire connected with the antenna to be tested is inserted into the test seat, the first end of the test seat is disconnected with the test wire.
In this embodiment, when a test wire connected to an antenna to be tested is not inserted into the test socket, the first end of the test socket is electrically connected to the test wire; when a test wire connected to an antenna to be tested is inserted into the test socket, the first end of the test socket is disconnected from the test wire. Thereby facilitating testing using the test line.
Optionally, the inductance values of the inductors of different radio frequency sub-circuits are the same.
In this embodiment, the inductors of different rf sub-circuits have the same inductance, so that the circuit configuration can be simplified.
Optionally, the antenna to be measured is a 5G antenna.
In this embodiment, the antenna to be tested is a 5G antenna, so that the problem of occupation of a chip detection port by a 5G multi-antenna design requirement can be solved.
The antenna detection circuit provided by the embodiment of the utility model comprises at least two radio frequency sub-circuits and a first resistor R1, wherein each radio frequency sub-circuit comprises a test seat 1 and an inductor L; the first end of the inductor L is connected with the first end of the test socket 1, and the second end of the inductor L is grounded; the first end of the test socket 1 is connected with the radio frequency conduction end, and the grounding end of the test socket 1 is grounded; the detection ends of the test socket 1 of different radio frequency sub-circuits are all connected with a power supply, the detection ends of the test socket 1 of different radio frequency sub-circuits are also all connected with a first end of the first resistor R1, and a second end of the first resistor R1 is connected with a level detection unit; under the condition that a test wire connected with an antenna 2 to be tested is not inserted into the test socket 1, the detection end of the test socket 1 is disconnected with the grounding end; when a test wire connected to the antenna 2 to be tested is inserted into the test socket 1, the detection end of the test socket 1 is electrically connected to the ground. Therefore, the judgment logic of the antenna detection circuit is changed, namely when the terminal equipment designs a multi-channel multi-antenna, the terminal equipment is judged to be in the conduction test state as long as more than one radio frequency channel is detected to be in the conduction test state, and the state of the terminal equipment is not adjusted. The terminal state is adjusted only if all paths are in the coupled radiating state. The antenna detection circuit design can simplify the number of the main chip antenna detection ports to only one, thereby simplifying the detection process and saving the cost. The layout space of the circuit board is improved, and meanwhile the problem that the 5G multi-antenna design requires occupation of a chip detection port can be solved.
