Embodiments of the present application are not limited in this regard.

The terminal device in fig. 1, for example, the terminal device 1030 or the terminal device 1031, is a device having a wireless transceiving function. Specifically, the terminal device may be deployed on land, including indoor or outdoor, hand-held, wearable or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.).

The terminal device may be fixed or mobile. The heaven and earth integrated network system shown in fig. 1 may also comprise more or fewer terminal devices.

The satellite 101 mainly provides wireless access service for terminal devices, schedules wireless resources for the accessed terminal devices, and provides reliable wireless transmission protocols and data encryption protocols. Specifically, the satellite 101 is a satellite made of an artificial earth and/or an aerial vehicle, etc., and is a repeater for wireless communication. The satellite 101 may be: geostationary orbit (geostationary earth orbit, GEO) satellites, also known as geostationary orbit satellites or high orbit satellites; earth-middle orbit (medium earth orbit, MEO) satellites, also known as medium orbit satellites; and Low Earth Orbit (LEO) satellites, also known as low earth orbit satellites. Wherein the orbit height of the GEO satellite is 35786 kilometers (km), the orbit height of the MEO satellite is 2000 km-356 km, and the orbit height of the LEO satellite is 300 km-2000 km.

Ground station 102, also known as a satellite ground station (satellite earth stations), may transmit data to satellite 101, and may also receive data forwarded by other communication devices via satellite 101. Generally refers to ground equipment disposed on the surface of the earth, including on a ship or aircraft, for satellite communications.

As shown in fig. 1, satellite 101 may be in communication with terminal devices (terminal device 1030 and/or terminal device 1031), and may be, for example, terminal device 1030 and/or terminal device 1031 transmitting data to satellite 101, satellite 101 receiving the transmitted data from terminal device 1030 and/or terminal device 1031 and processing the transmitted data from terminal device 1030 and/or terminal device 1031. Alternatively, satellite 101 can also communicate with ground station 102 to cooperatively process received transmitted data from terminal device 1030 and/or terminal device 1031.

In the integrated network shown in fig. 1, any one of the communication devices (e.g., the satellite 101, the ground station 102, and the terminal device) has the capability of receiving data and transmitting data, and then any one of the communication devices may be referred to as a transmitting device or a receiving device. For example, satellite 101 may transmit data to a terminal device and ground station 102, ground station 102 and terminal device receiving the transmitted data from satellite 101; alternatively, the ground station 102 may transmit data to the satellite 101, and the satellite 101 may receive the data transmitted from the ground station 102.

When the terminal device transmits data to the satellite 101, the terminal device modulates the data to be transmitted into transmittable electromagnetic waves, and transmits the electromagnetic waves carrying the data to the satellite 101, so that the satellite 101 needs to receive the electromagnetic waves carrying the data transmitted by the terminal device, and also needs to process the electromagnetic waves carrying the data transmitted by the terminal device, so as to obtain the data transmitted by the terminal device.

In order to acquire data transmitted by a terminal device, referring to fig. 2, in the satellite 101, an antenna 201 and a receiver 202 are generally disposed, where the antenna 201 is used to receive electromagnetic waves that are transmitted by the terminal device and carry the transmitted data, the electromagnetic waves that are transmitted by the terminal device and carry the transmitted data are transmitted to the receiver 202, and the electromagnetic waves that are transmitted by the terminal device and carry the transmitted data are processed by the receiver 202.

Illustratively, where receiver 202 is a superheterodyne receiver, the superheterodyne receiver includes a high frequency amplifier 2021, a mixer 2022, a local oscillation source 2023, an intermediate frequency amplifier 2024, and a demodulator 2025.

Then, the antenna 201 is used for transmitting the received electromagnetic wave carrying the transmission data transmitted by the terminal device to the high frequency amplifier 2021. The high-frequency amplifier 2021 is configured to amplify the electromagnetic wave carrying the transmission data transmitted by the terminal device, where the electromagnetic wave carrying the transmission data transmitted by the terminal device is attenuated in the process of being transmitted to the satellite 101 because the distance between the satellite 101 and the terminal device is relatively large, and the power of the attenuated electromagnetic wave is small, so that the high-frequency amplifier 2021 is required to amplify the electromagnetic wave carrying the transmission data transmitted by the terminal device, and the high-frequency amplifier 2021 amplifies only the interesting part of the electromagnetic wave carrying the transmission data transmitted by the terminal device, so as to generate a high-frequency signal, and then transmit the high-frequency signal to the mixer 2022.

The local oscillation source 2023 is configured to generate a signal with a fixed frequency, which is called a local oscillation signal, where the frequency of the local oscillation signal is higher than that of the high frequency signal, and transmit the local oscillation signal to the mixer 2022. The mixer 2022 mixes the local oscillation signal with the high-frequency signal to generate an intermediate frequency signal, and transmits the intermediate frequency signal to the intermediate frequency amplifier 2024. An intermediate frequency amplifier 2024 for amplifying the intermediate frequency signal to increase the gain, and then transmitting the intermediate frequency signal to the demodulator 2025. And a demodulator 2025, configured to obtain, according to the intermediate frequency signal, transmission data in the electromagnetic waves carrying the transmission data transmitted by the terminal device, so as to implement communication between the terminal device and the satellite.

However, the rate at which the terminal devices in the existing integrated network will sense the transmitted data is limited because the signal-to-noise ratio of the receiver deployed in the satellite 101, which receives the electromagnetic wave carrying the transmitted data transmitted by the terminal device, is not high enough. The magnitude of the signal-to-noise ratio of the electromagnetic wave carrying the transmission data transmitted by the receiver receiving the terminal device depends on the transmission power of the transmitter in the terminal device, the transmission loss of the transmission channel between the terminal device and the satellite 101, and the reception sensitivity of the antenna disposed in the satellite 101.

In a certain integrated network, the transmission distance between the terminal device and the satellite 101 is relatively long, and the transmission loss is relatively large. And because the terminal devices tend to be relatively small, the transmit power of the transmitters in the terminal devices is limited. Then, in order to improve the signal-to-noise ratio of the electromagnetic wave carrying the transmission data transmitted by the receiver receiving terminal device in the satellite 101, this can be achieved by improving the sensitivity of the reception of the antenna disposed in the satellite 101.

Referring to fig. 3, an embodiment of the present application provides an antenna 30, the antenna 30 being deployable in the satellite 101 and/or the ground station 102 shown in fig. 1, the antenna 30 comprising: a reflective structure 301 and a two-dimensional array of reed burgers 302; a reflective structure 301 for receiving a first electromagnetic wave, e.g. the first electromagnetic wave may be emitted by a transmitting device; the reflecting structure 301 is also used for reflecting the first electromagnetic wave. Specifically, as shown in fig. 1 and fig. 3, the transmitting device may be a terminal device, and then the first electromagnetic wave is an electromagnetic wave carrying transmission data that is transmitted to the satellite 101 by the terminal device, and the antenna 30 is disposed in the satellite 101; alternatively, the transmitting device may be the satellite 101, and then the first electromagnetic wave is the electromagnetic wave that the satellite 101 transmits to the ground station 102 and carries the transmission data, and the antenna 30 is disposed in the ground station 102; still alternatively, the transmitting device may be the ground station 102, and then the first electromagnetic wave is an electromagnetic wave that the ground station 102 transmits to the satellite 101 carrying the transmitted data, and the antenna 30 is disposed in the satellite 101. After the transmitting device transmits the first electromagnetic wave, the reflecting structure 301 in the antenna 30 receives the electromagnetic wave transmitted by the transmitting device and reflects the first electromagnetic wave.

A two-dimensional array 302 of reed burgers for receiving the first electromagnetic wave reflected by the reflecting structure 301; the two-dimensional array 302 of Redbergs includes a plurality of Redberg vapor bubbles distributed in an array; the reed-burger vapor bubble is used for generating a detection signal according to the first electromagnetic wave and outputting the detection signal, and for example, the detection signal can be transmitted to a receiver. Specifically, referring to fig. 4, the two-dimensional array 302 of reed burg includes an array of N rows by M columns of reed burg vapor bubbles 400. Illustratively, each of the Redberg vapor bubbles 400 is approximately 1 cubic centimeter, and the distance between any two of the Redberg vapor bubbles 400 is 0.5 centimeters to facilitate the in-process fabrication of the two-dimensional array of Redbergs 302. And, the two-dimensional array of reed burg 302 is configured to receive the first electromagnetic wave reflected by the reflecting structure 301, and the first electromagnetic wave is reflected to the reed burg vapor bubble 400 in the two-dimensional array of reed burg 302 along the direction of the z-axis (or along the direction having a predetermined angle with the z-axis). The reed burg vapor bubble 400 in the two-dimensional array 302 is then used to generate a detection signal from the first electromagnetic wave and transmit the detection signal to a receiver. The detection signal received by the receiver may be that the receiver selects a predetermined number of the reed burg vapor bubbles 400 to transmit the detection signal, or the receiver receives the detection signal generated by each reed burg vapor bubble 400.

In the above antenna, the reflection structure reflects the first electromagnetic wave received from the transmitting device to the two-dimensional array of reed burg, where the two-dimensional array of reed burg includes reed burg vapor bubbles distributed in array, and after the reed burg vapor bubbles receive the first electromagnetic wave, the reed burg vapor bubbles can detect the first electromagnetic wave to generate a detection signal, and when the detection signal is transmitted to the receiver, the receiver obtains the transmitting data transmitted by the transmitting device from the first electromagnetic wave. The reaction of the reed-burg steam bubble in the reed-burg two-dimensional array to the first electromagnetic wave is sensitive, so that when the reed-burg two-dimensional array is deployed in the antenna, the sensitivity of the antenna for receiving the first electromagnetic wave is further improved, and after the sensitivity of the antenna for receiving the first electromagnetic wave is high, the signal-to-noise ratio of a receiver connected with the antenna for receiving the first electromagnetic wave is synchronously increased.

Where, referring to fig. 4, the first electromagnetic wave is reflected to the reed burg vapor bubble 400 in the two-dimensional reed burg array 302 along the z-axis (or along a direction having a predetermined angle with the z-axis), then, in order to implement the generation of the detection signal by the reed burg vapor bubble 400 according to the first electromagnetic wave, it is further necessary to provide a control beam and a detection beam to each of the reed burg vapor bubbles 400, as shown in fig. 4, the detection beam provided to the reed burg vapor bubble 400 may be a direction-x to-x through the reed burg vapor bubble, and the control beam provided to the reed burg vapor bubble 400 may be a direction x to-x through the reed burg vapor bubble.

By way of example, referring to FIG. 5, an embodiment of the present application provides a schematic structural diagram of a Redberg vapor bubble 400, wherein the Redberg vapor bubble 400 includes a gas chamber 401 and a mixed atomic gas disposed in the gas chamber 401, the mixed atomic gas including a Redberg atom and an inert gas; illustratively, the reed burg atoms include one or more of the following: lithium, sodium, potassium, cesium and rubidium atoms, the inert gas comprising one or more of the following: helium atomic gas, neon atomic gas, argon atomic gas, krypton atomic gas, xenon atomic gas. The air cell 401 is connected to a laser 51 and a laser 52; after the two-dimensional array of the reed burgers receives the first electromagnetic wave reflected by the reflecting structure, the first electromagnetic wave is actually transmitted to each of the two-dimensional array of the reed burgers 400 along the direction of the z-axis (or along the direction having a predetermined angle with the z-axis), and the air cells 401 in the two-dimensional array of the reed burgers 400 are mainly used for receiving the first electromagnetic wave.
