Referring to fig. 3, fig. 3 is a first structural schematic diagram of an antenna device according to an embodiment of the present disclosure. The antenna apparatus includes a first rf transceiver 310, a first switch 320, a second rf transceiver 410, and a second switch 420.
The first rf transceiver 310 is configured to receive and transmit at least two rf signals, which may specifically include a first rf signal, a second rf signal, and a third rf signal, and an output end of the first rf transceiver 310 is connected to the combiner 360, so that the first rf signal, the second rf signal, and the third rf signal are combined. The above-described antenna apparatus may further include a matching circuit combination including a plurality of matching circuits, such as a first matching circuit 330, a second matching circuit 340, a third matching circuit 350, a fourth matching circuit 430, and a fifth matching circuit 440, respectively. The first switch 320 has one end connected to the combiner 360 and the other end connected to the first matching circuit 330, the second matching circuit 340 and the third matching circuit 350, and the first switch 320 is configured to selectively turn on one of the first matching circuit 330, the second matching circuit 340 and the third matching circuit 350 according to a current radiation mode. The second rf transceiver 410 is configured to transceive at least one rf signal, such as a fourth rf signal, one end of the second switch 420 is connected to the second rf transceiver 410, and the other end is connected to the fourth matching circuit 430 and the fifth matching circuit 440, respectively, and the second switch 420 is configured to selectively switch on one of the fourth matching circuit 430 or the fifth matching circuit 440 according to a current radiation pattern. The first type of radio frequency signals received and transmitted by the first radio frequency transceiver and the second type of radio frequency signals received and transmitted by the second radio frequency transceiver have different radio frequency bands.
In an embodiment, the antenna apparatus may further include a radiator 510, and the radiator 510 is electrically connected to the first matching circuit 330, the second matching circuit 340, the third matching circuit 350, the fourth matching circuit 430 and the fifth matching circuit 440, respectively, to receive and transmit a first radio frequency signal, a second radio frequency signal, a third radio frequency signal and a fourth radio frequency signal.
For example, the first rf signal may be a WI-FI signal, the second rf signal may be a bluetooth signal, the third rf signal may be a GPS signal, and the fourth rf signal may be an LTE signal.
In an embodiment, the first matching circuit 330 is configured to transmit signals in a first rf signal band, a second rf signal band and a third rf signal band, and the fourth matching circuit 430 is configured to transmit signals in a fourth rf signal band that do not overlap with the first rf signal band, the second rf signal band and the third rf signal band. For example, the first radio frequency signal may be a WI-FI signal, where the WI-FI signal may further include a 2.4GWI-FI signal and a 5GWI-FI signal, an operating frequency band corresponding to the 2.4GWI-FI signal may include 2400MHz-2483 MHz, and an operating frequency band corresponding to the 5GWI-FI signal may include 5150MHz-5825 MHz. The second radio frequency signal may be a bluetooth signal, an operating frequency band corresponding to the bluetooth signal may include 2400MHz to 2485MHz, the third radio frequency signal may be a GPS signal, and an operating frequency band corresponding to the GPS signal may include 1200MHz to 1600 MHz. The first matching circuit 330 is used to transmit signals having frequencies in the 1200MHz-1600MHz, 2400MHz-2485MHz, and 5150MHz-5825 MHz bands. The fourth radio frequency signal may be an LTE signal, the working frequency band corresponding to the LTE signal may include 700MHz-960MHz, 1710MHz-2170MHz, and 2300MHz-2690MHz, and since the fourth matching circuit 430 is configured to transmit the fourth radio frequency signal frequency band and signals that do not overlap with the first radio frequency signal frequency band, the second radio frequency signal frequency band, and the third radio frequency signal frequency band, the fourth matching circuit is configured to transmit signals whose frequencies are within 700MHz-960MHz, 1710MHz-2170MHz, 2300MHz-2400MHz, and 2485MHz-2690 MHz.
When the radiation mode is to simultaneously transmit and receive the first rf signal, the second rf signal, the third rf signal, and the fourth rf signal, the first switch 320 selectively turns on the first matching circuit 330, and the second switch 420 selectively turns on the fourth matching circuit 430. For example, when the user is running with the smart watch and needs to use the LTE signal, the WI-FI signal, the bluetooth signal, and the GPS signal at the same time, the first switch 320 is controlled to switch on the first matching circuit 330, and the second switch 420 is controlled to select to switch on the fourth matching circuit 430, so that the performance of receiving and transmitting signals in each frequency band is relatively balanced. The first switch 320 may be a single-pole-three-throw switch, and the second switch 420 may be a single-pole-two-throw switch.
In one embodiment, the fifth matching circuit 440 may be configured to transmit signals of the entire frequency band of the fourth rf signal. For example, when the second radio frequency transceiver receives and transmits LTE signals, that is, the fourth radio frequency signal is an LTE signal, the fifth matching circuit is used for transmitting signals with frequencies within a range of 700MHz to 960MHz, 1710MHz to 2170MHz, and 2300MHz to 2690 MHz.
When the radiation mode is only transmitting and receiving a fourth rf signal, the first switch 320 selectively switches on any one of the first matching circuit 330, the second matching circuit 340, or the third matching circuit 350, and the second switch 420 selectively switches on the fifth matching circuit 440. It should be noted that, in the current radiation mode, the antenna apparatus can only transmit and receive the fourth rf signal, and in addition, can also simultaneously transmit other rf signals, such as the first rf signal, the second rf signal, or the third rf signal, but only can transmit and cannot receive such rf signals. For example, if the smart watch turns on an eSIM (Embedded-SIM) service and is not connected to other devices and does not need to be located, the radiation mode of the smart watch is only to receive and transmit LTE signals, and at this time, the first switch 320 is controlled to switch on any matching circuit, and the second switch 420 is controlled to select to switch on the fifth matching circuit 440, so that the performance of receiving and transmitting LTE signals is optimal. The eSIM card is a concept in which a conventional SIM card is directly embedded in a chip of a device, rather than being added to the device as a separate removable component, and a user does not need to insert a physical SIM card.
Further, in the above embodiment, if the radiation mode is only to receive and transmit the fourth radio frequency signal, that is, the LTE signal, at this time, the WIFI signal and the bluetooth signal may also be transmitted to the outside, for example, the WIFI and the bluetooth scan the surrounding devices, but the WIFI and the bluetooth are only scanned and are not used, so that the WIFI and the bluetooth are kept scanning, which is to consider that the device may be suddenly connected to the WIFI and the bluetooth. Therefore, at this time, it is not necessary to keep the antenna performance of WIFI or bluetooth optimal, and the first switch 320 may select to turn on any one of the first matching circuit 330, the second matching circuit 340, and the third matching circuit 350.
In an embodiment, please refer to fig. 4, fig. 4 is a second structural schematic diagram of the antenna apparatus provided in the embodiment of the present application, wherein the antenna apparatus may further include a radio frequency switch 450, two ends of the radio frequency switch 450 are respectively connected to the second radio frequency transceiver 410 and the second switch 420, and the radio frequency switch 450 is configured to control a connection state of the fourth radio frequency signal transceiving path, for example, the path may be controlled to be in a connection state or a disconnection state.
In an embodiment, the antenna apparatus may further include a radiator 510, and the radiator 510 is electrically connected to the first matching circuit 330, the second matching circuit 340, the third matching circuit 350, the fourth matching circuit 430 and the fifth matching circuit 440, respectively, to receive and transmit a first radio frequency signal, a second radio frequency signal, a third radio frequency signal and a fourth radio frequency signal.
