Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
As described in the background art, a conventional phased array antenna is composed of an antenna array, a transceiver module, a feeding system, a calibration system, a power supply system, and a control system, and the modules are designed independently from each other and connected to each other through a connector. For example, for the feeding system, a PCB (Printed Circuit Board) Circuit Board may be configured; for a power supply system, it is possible to configure another PCB circuit board; for a control system, an independent PCB may be configured, so that the whole phased array antenna has the problems of low integration level, large volume, high cost, and the like.
In view of the above, in order to solve the above problems, the present application provides a phased array antenna, which achieves the purpose of reducing the size and cost of the phased array antenna by integrating a plurality of modules on the same PCB.
The following is an exemplary illustration of a phased array antenna provided by the present application:
as an implementation manner, referring to fig. 1, a phased array antenna 100 includes an antenna array 110, a control system 120, a power system 130, a power supply system 140, and a transceiver module 150, where the antenna array 110, the control system 120, the power system 130, the power supply system 140, and the transceiver module 150 are integrated on the same PCB and arranged in layers, a metal ground 160 is connected between the antenna array 110 and the control system 120, and a metal ground 160 is also connected between the power system 130 and the power supply system 140. The feeding system 140 is connected to the transceiver module 150, and the antenna array 110, the control system 120, and the power system 130 are all provided with a metal hole 170 penetrating through the transceiver module 150, the metal hole 170 is disposed at a distance from the metal ground 160, and the antenna array 110, the control system 120, and the power system 130 are all connected to the transceiver module 150 through the metal hole 170.
Through the implementation mode, all the systems are integrated on the same PCB, and then the effects of high integration level, small size, low cost and good reliability can be achieved.
Optionally, the antenna array 110 provided by the present application is in the form of a microstrip antenna, and the microstrip patch antenna has the advantages of small volume, light weight, low profile, easy processing, and convenient integration with other modules. The antenna array 110 can receive and transmit radio frequency signals, and transmit the received signals to the transceiver module 150.
Please refer to fig. 2, the transceiver module 150 selects a multifunctional low-cost microwave rf chip, and has multiple rf channels to implement the functions of rf signal amplification, amplitude modulation, phase modulation, power detection, and the like, and an external digital signal can control the chip. That is, the transceiver module 150 includes a plurality of microwave rf chips, and each of the microwave rf chips is connected to the antenna array 110. In addition, the number of channels for transmitting and receiving is 5, which are 1 channel, 2 channel, 4 channel, 8 channel and 16 channel.
The feed system 140 adopts a power dividing network in the form of a microstrip line or a strip line to realize the distribution or combination of radio frequency signals. In one implementation, the transceiver module 150 is soldered to the power feeding system 140. The power supply system 130 supplies power to the transceiver module 150 by etching a specific line on the PCB, thereby ensuring the normal operation of the transceiver module 150. The control system 120 realizes the functions of amplitude modulation, phase modulation, power detection, and the like of the transceiver module 150 by etching a specific line on the PCB.
In a possible implementation manner, the transceiver module 150 is provided with a control interface and a power interface, the control interface and the power interface are respectively connected to each microwave rf chip in the transceiver module 150, and meanwhile, the power system 130 and the control system 120 are connected to the transceiver module 150 through the metal hole 170, so as to realize power supply and control of each microwave rf chip.
In one implementation, the antenna array 110, the control system 120, the power system 130, the power feeding system 140, and the transceiver module 150 are arranged layer by layer. In order to eliminate the mutual influence between the modules, in this implementation, a metal ground 160 is provided between the antenna array 110 and the control system 120, and a metal ground 160 is provided between the power supply system 130 and the power feeding system 140.
As another implementation manner, referring to fig. 3, the antenna array 110, the power system 130, the control system 120, the feeding system 140, and the transceiver module 150 are disposed layer by layer, and on this basis, a metal ground 160 is connected between the antenna array 110 and the power system 130, and a metal ground 160 is connected between the control system 120 and the feeding system 140.
Since the influence between the power system 130 and the control system 120 is relatively small, a metal ground 160 may be disposed between the power system 130 and the control system 120, or may be directly connected, and the metal ground 160 is not disposed, which is not limited in this application.
It should be noted that, in the actual manufacturing process, the metal hole 170 is generally manufactured by drilling the phased array antenna, then plating metal on the inner wall of the hole to form the metal hole 170, and in order to facilitate connection between other modules and the transceiver module 150, the present application uniformly adopts the way of the metal hole 170 to perform connection. However, since the metal ground 160 may be disposed between two adjacent modules or systems, if the metal hole 170 is connected to the metal ground 160, the metal hole 170 is short-circuited, and signals cannot be transmitted, for example, the power system 130 is connected to the transceiver module 150 through the metal hole 170, and the metal ground 160 is disposed between the power system 130 and the power feeding system 140, so that if the metal hole 170 is connected to the metal ground 160, the power system 130 is short-circuited, and power cannot be normally supplied to the transceiver module 150.
In view of this, as a possible implementation manner of the present application, the outer side of the metal hole 170 is covered with a non-metal layer, so that the metal hole 170 and the metal ground 160 are disposed at a distance. In other words, after drilling the phased array antenna, the inner walls of the holes may be coated with a non-metal layer and then plated with metal, thereby achieving no contact between the metal holes 170 and the metal ground 160. Of course, in other embodiments, it is possible to achieve non-contact between the metal hole 170 and the metal ground 160 in other ways, for example, when drilling, the hole of the metal ground 160 layer is larger than the diameter of the metal hole 170, so that the metal hole 170 is not in contact with the metal ground 160.
In addition, in order to realize the self calibration of the phased array antenna and simultaneously monitor whether the transceiver module 150 is normal, the phased array antenna further includes a calibration system 180, the calibration system 180 is also integrated on the PCB, and the calibration system 180 is connected with the transceiver module 150.
As an implementation manner, referring to fig. 4, the calibration system 180 is located between the power feeding system 140 and the power supply system 130, and a metal ground 160 is connected between the calibration system 180 and the power supply system 130, on this basis, the metal ground 160 is also connected between the calibration system 180 and the power feeding system 140, and the calibration system 180 is provided with a metal hole 170 penetrating through to the transceiver module 150.
As another implementation, calibration system 180 is located at the same level as feed system 140. Based on this, the calibration system 180 can be directly connected to the transceiver module 150 without passing through the metal via 170.
It should be noted that the antenna array 110, the control system 120, the power system 130, the calibration system 180, and the power feeding system 140 all include one or more metal layers, and the ends of the metal holes 170 are connected to the metal layers. In other words, the number of layers of the antenna array 110, the control system 120, the power system 130, the calibration system 180, and the feeding system 140 may be greater than or equal to 1 layer.
Meanwhile, the metal layer is a copper layer, and the copper layer are filled with a medium, wherein the antenna array surface 110, the calibration system 180 and the feeding system 140 are microwave media, the relative dielectric constant of the microwave media is in a range of 2-100, and the loss tangent is in a range of 10-4-10-2.
Based on the above implementation, the present application further provides an antenna module, which includes the above phased array antenna.
In summary, the present application provides a phased array antenna and an antenna module, where the phased array antenna includes an antenna array surface, a control system, a power system, a feed system, and a transceiver module, the antenna array surface, the control system, the power system, the feed system, and the transceiver module are all integrated on the same PCB and arranged in layers, a metal ground is connected between the antenna array surface and the control system, and a metal ground is also connected between the power system and the feed system; the feed system is connected with the transceiver module, the antenna array surface, the control system and the power supply system are all provided with metal holes penetrating through the transceiver module, the metal holes are arranged at a distance from a metal ground, and the antenna array surface, the control system and the power supply system are all connected with the transceiver module through the metal holes. Through the phased array antenna that this application provided, realize can be with a plurality of systems integration on same PCB board, and then need not independent design, the integrated level is higher, the volume is littleer and effectively the cost is reduced.
