Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of communication antennas, and more specifically, to dielectric phase shifters, antenna arrays, and antennas. Background Technology

[0002] With the development of fifth-generation mobile communication technology (5G), more and more communication frequency bands are being used. To obtain accurate communication signals, the number of antenna components is gradually increasing. Phase shifters can control the phase of the antenna, resulting in more accurate signal direction and better signal coverage. Phase shifters are widely used in communication systems, especially in mobile communication systems.

[0003] Phase shifters can create a specific phase difference between antenna elements and cause electromagnetic waves to superimpose in a specified direction. Using phase shifters, antennas can generate precise beam direction, thereby reducing unwanted signal interference from nearby communication network sectors.

[0064] The principles of this disclosure will now be described with reference to several exemplary embodiments illustrated in the accompanying drawings. Although exemplary embodiments of this disclosure are shown in the drawings, it should be understood that these embodiments are described only to facilitate a better understanding and implementation of this disclosure by those skilled in the art, and not to limit the scope of this disclosure in any way.

[0066] As mentioned above, in the use of electrically tuned phase shifters, lighter weight, lower cost, and better performance are becoming increasingly important for communication systems, especially for fifth-generation radio modules. There are two common types of electrically tuned phase shifters: analog and digital. Digital phase shifters are generally lightweight and low-cost, but their radio performance is less desirable, with issues such as loss and PIM (Power Injection Mold). Analog electrically tuned phase shifters are popular in radio communication systems, particularly in frequency division duplex (FDD) radio systems, due to their superior radio performance.

[0067] Analog electronically tuned phase shifters typically consist of a U-shaped or circular dielectric insert. The traces of the phase shifter are usually printed circuit board (PCB) circuitry within the dielectric component. The phase of the antenna containing the phase shifter can be adjusted by changing the connection area between the dielectric component and the metal component. Analog electronically tuned phase shifters usually require an additional metal shield / cover on the dielectric component. This shield / cover can be manufactured by die casting or extrusion. This type of phase shifter is relatively heavy and involves a complex assembly process during manufacturing. This type of phase shifter typically requires additional volume, which affects radiation performance. This type of phase shifter is not flexible for antenna design. This type of phase shifter typically requires many solder joints, such as PCB circuit solder joints and shield / cover solder joints. Due to the presence of solder joints, achieving a high level of PIM (Position Injection Model) is difficult.

[0068] To achieve better PIM and lower losses, metal sheets can be used instead of PCB circuits with additional shielding covers / covers on the dielectric components. However, the weight remains significant, the assembly process is complex, and assembly errors are possible. If the shielding cover / cover is partially open, EMC will be reduced, and unwanted coupling in nearby communication paths can be increased.

[0069] To address the problems described above, this paper presents a novel integrated dielectric phase shifter. This dielectric phase shifter achieves better radiation performance, lighter weight, and reduced cost. Furthermore, the assembly process of the dielectric phase shifter during manufacturing is simple.

[0070] The dielectric phase shifter described herein typically includes a sheet metal component, a dielectric component, and a remote electrical tilt (RET) actuation component. The dielectric phase shifter described herein does not require an additional shielding cover / cover. The shielding function of the dielectric phase shifter can be achieved through recesses in a power divider board. The recesses have an internal metal plating that shields against external unwanted signals, thereby achieving better EMC values. The recesses in the power divider board also provide grounding (GND) for the dielectric phase shifter. Therefore, compared to conventional dielectric phase shifters, the weight of the dielectric phase shifter according to embodiments of this disclosure can be significantly reduced.

[0071] Furthermore, according to embodiments of this disclosure, the position of the recess on the power divider board can be adjusted based on different antenna designs. Therefore, the dielectric phase shifter offers greater flexibility in its placement within the antenna compared to conventional dielectric phase shifters with additional shielding / covers. Additional shielding / covers typically occupy a large volume and negatively impact the antenna's radiation performance.

[0072] Furthermore, according to embodiments of this disclosure, the metal sheet of the dielectric phase shifter is connected to the power divider circuit on the power divider board via several dielectric pads (such as plastic pads). The assembly process typically involves riveting the bottom side of the reflector component. In this way, no additional solder joints are required when the dielectric phase shifter is connected to the power divider board, thus simplifying the manufacturing process and achieving better PIM performance.

[0073] Furthermore, according to embodiments of this disclosure, the actuating component can be used to adjust the length of the medium on the metal sheet via a series of gears. A vertical drive rod can drive a horizontal drive rod via gears, and the horizontal drive rod can drive the medium component to move via a series of gears. The vertical drive rod can be connected to an additional drive mechanism, such as a motor. The actuating component can simultaneously adjust the phase of all communication paths, resulting in a stable and consistent phase. In this way, the antenna can achieve precise downtilt and good beam performance.

[0074] According to embodiments of this disclosure, antennas with such dielectric phase shifters will have better radio frequency (RF) performance as well as reduced weight, size, and cost. The phase shifter does not require solder joints during manufacturing, which enables good PIM performance. Reference will be made below to... Figure 1A-18 The principles of this disclosure are described in detail.

As shown in the figure, antenna 300 further includes a reflector plate 18 spaced apart from the reflector member 15 of each antenna array 200. Actuation member 13 is disposed on the reflector plate 18 and located between the reflector plate 18 and the reflector member 15.

[0113] It should be understood that the first and second media members 121, 122 may be driven to move in other ways than by using gears. The scope of this disclosure is not intended to be limited in this respect.

The upper layer 1231 and the lower layer 1232 may surround a first portion 1101 of the first metal sheet 111 and a third portion 1103 of the second metal sheet 112.

[0120] In one embodiment, the upper layer 1231 and the lower layer 1232 may have substantially the same thickness.

[0121] In some embodiments, each of the first overlapping member 1231 and the second overlapping member 1232 may comprise a single layer, rather than two layers, disposed above a first portion 1101 of the first metal sheet 111 or a third portion 1103 of the second metal sheet 112. The length of the medium on the metal sheet can be adjusted by moving the first dielectric member 121, thereby allowing the phase of the signal to be transmitted to be tuned.

Figure 16 Is it like this? Figure 15AThe diagram shows an exploded view of the antenna. As shown, in this embodiment, antenna 300 includes eight antenna arrays 200. Each antenna array 200 may have the features described above. Figure 12A-14 The structure described herein will not be described in detail here. As shown in the figure, antenna 300 further includes a reflector plate 18 spaced apart from the reflector member 15 of each antenna array 200. Actuation member 13 is disposed on the reflector plate 18 and located between the reflector plate 18 and the reflector member 15.
