The surroundings of the antenna to be monitored may include: a hand-held area of the terminal device, a bottom area of the terminal device, a back area, a circumference of the earpiece, a periphery of the microphone, and the like. For example, the hand-held area includes a palm coverage area and a finger coverage area, and the antenna to be monitored is located in the finger coverage area, and the infrared temperature sensor is disposed in the palm coverage area. When the temperature signal monitored by the infrared temperature sensor is greater than or equal to the temperature threshold, the handheld area is indicated. Blocked, the processor determines that the antenna to be monitored corresponding to the finger coverage area is blocked. The antenna to be monitored corresponds to one antenna, and the antenna to be monitored may correspond to multiple antennas or one antenna.

Each thermistor sensor is located at each antenna. The thermistor sensor has the characteristics of small size and low price, and its size is about 1 mm, but the measurement temperature is slower. According to the above characteristics of the thermistor sensor, the thermistor sensor is placed close to the antenna, corresponding to the antenna, which saves space on the one hand, and closes the antenna on the other hand to overcome the shortcoming of slow response.

The infrared temperature sensor acquires external temperature information by detecting external heat radiation, and has the characteristics of large volume and fast reaction speed, and its size is generally about 5 mm. According to the above characteristics of the infrared temperature sensor, the infrared temperature sensor can be placed around the antenna to be monitored.

The infrared reflection sensor uses the principle of infrared reflection to emit infrared rays and determine the presence or absence of obstacles in front based on the intensity of reflection. The infrared reflection sensor sends an infrared feedback signal to the processor when an object approaches and blocks reflection of the infrared. The infrared reflection sensor is also used to monitor whether the antenna is blocked. Its specific characteristics are similar to those of the infrared temperature sensor, such as a large volume, and therefore also located around the antenna to be monitored. The difference between the infrared reflection sensor and the infrared temperature sensor is that the infrared temperature sensor depends on the temperature, so it can only monitor the human body to block the antenna. In addition to monitoring the human body to block the antenna, the infrared reflection sensor can also monitor other objects such as metal. The situation of the antenna. The effect of metal on the performance of the antenna is far more than that of the human body. Therefore, the infrared reflection sensor can simultaneously monitor the obstruction of the antenna by the human body and the metal.

When the antenna transmits high-frequency wireless signals, there are different radiated powers in different directions, so the antenna has directionality; if the antenna direction with smaller radiated power of the wireless signal is selected, the wireless performance of the terminal device may also be degraded. When the spatial direction of the terminal device changes, the antenna direction also changes. This requires selecting an antenna that can obtain optimal wireless performance in a specific direction.

According to the principle of inertia, the gyroscope can monitor the change of the direction of the terminal equipment, and the terminal equipment, and the change of the direction of the antenna will inevitably affect the radiated power of the antenna in different spaces. The gyroscope can be used to monitor the direction of the antenna of the terminal device.

The terminal device presets a correspondence table between the direction in which the antenna is located and the antenna efficiency index, and the antenna efficiency index in the corresponding direction in the correspondence table. When the processor determines the direction in which the antennas are located, the processor queries the antenna in the direction and the antenna efficiency index correspondence table and obtains the antenna efficiency index corresponding to each antenna in the current direction.

Wherein, the main lobe direction of the antenna means: If the intensity of the antenna radiated in each direction is represented by the length of the vector from the origin, the envelope formed by connecting all the vector end points is the antenna pattern. It shows the relative size of the antenna radiating in different directions. This pattern is called a stereogram. The direction of the radial axis represents the direction of the radiation, and the length of the radial path represents the intensity of the radiation strike. The pattern contains a number of lobes, and the lobes containing the largest radiation direction are called the main lobes.

When it is detected that one antenna (such as GPS antenna 1) is completely occluded, and the other antenna (such as GPS antenna 2) is not occluded, the other antenna (such as GPS antenna 2) is preferentially selected; In the case of occlusion, according to the attitude of the mobile phone fed back by the gyroscope (upright or horizontal screen use state), the antenna direction of the mobile phone is obtained, and it is decided to use an antenna with better wireless performance. As shown in Figure 2, after the antenna is selected, the baseband chip sends the antenna identification of the working antenna to the antenna switch. At the same time, the baseband chip sends the baseband signal to the radio frequency chip, and the radio frequency chip transmits the modulated radio frequency signal to the working antenna through the antenna switch to establish an RF signal path.

Set the monitoring frequency, for example: the antenna occlusion condition judgment period is 3 seconds, the antenna direction condition (mobile phone attitude) judgment time is 2 seconds, the selection period or the antenna switch control refresh time is 1 second; thus, every 1 second, The mobile phone reselects the antenna once; every 2 seconds, the gyroscope refreshes the terminal device direction signal; every 3 seconds, the temperature sensor refreshes the temperature signal, or the reflective infrared sensor refreshes the infrared feedback signal; this can minimize the mobile phone each The state of use or the influence of wireless signals caused by antenna occlusion ensures optimal GPS wireless performance. A seventh embodiment of the present invention provides a terminal device, including:

N antennas for wireless communication, N is a positive integer and N > 2;

The processor is further configured to select, as the working antenna, an antenna with the highest antenna efficiency index from the N antennas, and send an antenna identifier of the working antenna to the antenna switch; At least one of the N antennas is a multi-frequency antenna; each of the multi-frequency antennas is used as at least two antennas: a WIFI antenna, a GPS antenna, a main set antenna, a diversity antenna, a near field communication antenna, or Each of the multi-frequency antennas is used as at least two antennas: a Bluetooth antenna, a GPS antenna, a main set antenna, a diversity antenna, and a near field communication antenna;

The multi-frequency antenna refers to an antenna that receives wireless signals of at least two frequency bands. Since the signal transmission frequency of the wireless service is different, a multi-frequency antenna can be used to realize one antenna having multiple antenna functions. A multi-frequency antenna can be used as at least two antennas: WIFI antenna, GPS antenna, Bluetooth antenna, main set antenna, diversity antenna, Near Field Communication (NFC). For example, the frequency of the wireless signal of the WIFI service is 2.4 GHz to 2.5 GHz; the frequency of the wireless signal of the Bluetooth service is 2.4 GHz to 2.5 GHz; the frequency of the wireless signal of the GPS signal is 1575 ± 2 MHz in the GPS navigation system, in Russia In the Global Navigation Satellite System (GLONASS, GLObal NAvigation Satellite System), it is 1602 ± 5MHz, and in the Beidou satellite system is 1561 ± 2MHz. In the GSM service, only the main set antenna is used, and the frequency of the wireless signal includes 900MHz or 1800MHz; In the LTE network, the frequency of the uplink wireless signal in the wireless signal of the main set antenna includes 1.9 GHz, the frequency of the downlink wireless signal includes 2.1 GHz, and the frequency of the wireless signal of the diversity antenna includes 2.1 GHz; in addition, wireless of other frequencies is included Signals are not listed in the present invention. The multi-frequency antenna can be used as a WIFI antenna, a GPS antenna, a Bluetooth antenna, a main set antenna, and a diversity antenna according to the frequencies of the wireless signals of the WIFI service, the GPS service, the Bluetooth antenna, the main set antenna, and the diversity antenna, respectively. For example, if the frequency of a wireless signal received by a multi-frequency antenna is set to two frequency bands of 2.4 GHz to 2.5 GHz and 1575 ± 2 MHz, the multi-frequency antenna can be used as a WIFI antenna or a GPS antenna. However, the WIFI antenna and the Bluetooth antenna cannot be compatible in the same multi-frequency antenna, that is, a multi-frequency antenna cannot be used as both a WIFI antenna and a Bluetooth antenna.

In the case of using a multi-frequency antenna as a plurality of antennas, in order to avoid business conflicts, To select an antenna in an idle state. For example, a multi-frequency antenna can be used as a WIFI antenna or a GPS antenna. In the case where the multi-frequency antenna has been used as a GPS antenna, if the terminal device also needs to use a WIFI antenna, the multi-frequency antenna cannot be selected as the WIFI antenna. For use, other idle antennas need to be selected because the multi-frequency antenna is already occupied by the GPS service.

Further, in the terminal device of the embodiment of the present invention, the processor is further configured to: control an operating frequency of the antenna monitoring module.

By controlling the operating frequency of the antenna monitoring module, it is possible to select the antenna with the best wireless performance according to the use scene of the terminal device in time.

FIG. 3 is a schematic structural diagram of a terminal device according to Embodiment 7 of the present invention. As shown in FIG. 3, for example, for a larger Internet PAD, that is, a tablet computer, especially paying attention to the WIFI indicator, the same requirement is required to support GPS. Due to the large PAD space, three WIFI available antennas can be set:

GPS/WIFI antenna 1 is a GPS and WIFI multi-frequency antenna, placed on the upper edge of the PAD;

WIFI antenna 2 is on the left side of the PAD;

WIFI antenna 3 is on the right side of the PAD;

The PAD determines the occlusion of the antenna through an infrared temperature sensor and a thermistor sensor. As shown in FIG. 3, the gyroscope is connected to the baseband chip, and sends the terminal device direction signal to the baseband chip; each of the antennas is provided with a thermistor sensor, for example, a thermistor sensor is disposed at the position of the GPS/WIFI antenna 1. 1. The position of the WIFI antenna 2 is provided with the thermistor sensor 2. The WIFI antenna 3 is provided with a thermistor sensor 3, and the thermistor sensor is connected to the baseband chip to send the temperature signal to the baseband chip; An infrared temperature sensor is arranged around the GPS antenna, and the infrared temperature sensor is connected to the baseband chip to send the temperature signal to the baseband chip.

The PAD antenna is specifically designed as follows: In free space (the antenna is unobstructed), the antenna efficiency index of the WIFI antenna 3 is better than that of the WIFI antenna 2, and is superior to the GPS/WIFI antenna 1, and the antenna efficiency index is increased by 1.5 dB in turn; and each antenna When occluded, the antenna efficiency index drops directly by 4dB.

The antenna selection strategy is as follows: When GPS is used, select other idle antennas. In the case of WIFI Internet access, select the antenna to be turned on between antennas 2 and 3. When not using GPS, In the case of WIFI Internet access, according to the occlusion of the antenna, the most efficient antenna that is not blocked is selected. As shown in Figure 3, after the antenna is selected, the baseband chip sends the antenna identifier of the working antenna to the antenna switch. At the same time, the baseband chip sends the baseband signal to the radio frequency chip, and the radio frequency chip transmits the modulated radio frequency signal to the working antenna through the antenna switch to establish a radio frequency signal path of the WIFI and the GPS service.

At the same time, the working frequency strategy is set, the monitoring period of the antenna occlusion condition and the antenna selection period can be set to 1 second, and every 1 second, the monitoring point signal is collected by the antenna monitoring module, and the antenna is reselected at the same time;

For example, the actual situation is that when using WIFI to access the Internet without using GPS, when the left hand holds the left side of the PAD, the WIFI uses the antenna WIFI on the right side to access the Internet; when the PAD is placed on the left and right sides of the leg, the antennas are blocked, and the upper part is not used. The occluded antenna is connected to the WIFI.

This makes WIFI wireless performance the best in all kinds of use cases. And since the antenna in the transmitting state avoids the human body, the radiation absorbed by the human body is also greatly reduced.
