At the end of 2017, the US Patent Trademark announced Apple's first eight-wood antenna (YAGI Antenna) patent. The millimeter wave antenna is likely to be applied in Apple's next generation 5G network equipment, and if all goes well, the millimeter wave 5G network will be launched in the United States between 2020 and 2021. However, the application of millimeter wave technology also includes a series of technical problems, including millimeter wave propagation, which is easily influenced by environmental factors, etc., and Apple, Apple, hopes to overcome through millimeters.
Apple pointed out in its patented background, and wireless communication that can support millimeter wave bands in the future. Millimeter wave communications sometimes referred to as extreme high frequency (EHF) involves approximately 10-400 GHz band. Operation on these frequencies may support higher bandwidth, but it may also bring considerable challenges. For example, millimeter wave communication is a typical line-up communication, which attenuates a large number of signals in the signal transmission process. Therefore, Apple wants to provide an improved wireless communication circuit to the electronic device, such as a communication circuit that supports millimeter wave communications.
Apple's invention is to improve wireless communication circuitry, such as a communication circuit that supports millimeter wave communications. Such wireless circuits may contain one or more antennas, and each antenna may contain phased antenna arrays, and many antenna units are included. The phase control antenna array may be used to process millimeter waves wireless communication and have an operation of performing beam regulation.
The phase antenna array may be mounted along the edge of the electronic device housing, after insulating sign or other antenna window on the back of the housing, it may also be aligned with the insulating housing portion of the housing angle, which may also be in electronics. Other places of equipment installation, related patents are shown in Figure 2.
The baseband processor may assign a wireless signal to the phase control antenna array on the intermediate frequency signal path with the intermediate frequency frequency. Transceiver circuits on the phase control antenna group may include an upper frequency converter and a downconverter coupled to an intermediate frequency signal path. Such an arrangement can minimize the path loss, by assigning the intermediate frequency frequency to the phase control antenna array and converts the intermediate frequency signal to the radio frequency signal of an antenna locally.
This printed circuit board antenna can include an eight-timber antenna. Each eight wood antenna can have a reflector, a heat sink, and one or more leaders. The electronic device can have a metal housing with a dielectric region. The dielectric region may be a tank filled in a metal casing or other dielectric region.
The reflector, the heat sink, and the guide can be configured such that each antenna has a radiation pattern aligned with the corresponding portion of the dielectric in the metal housing. In a printed circuit board having a plurality of substrate layers, different guide in the antenna can be embedded between different paired substrate layers to form a vertical orientation or diagonally oriented radiation pattern. The guides of the antenna can also be formed along the surface of the printed circuit board such that the antenna exhibits horizontally oriented radiation patterns. The antenna # 40 shown in FIG. 3 can be an eight-wood printed circuit board antenna or other suitable antenna in a patent specification.
In addition, Apple Patent Fig. 3 is a rear view of the Idevice in the illustrative configuration, wherein each angular # 50 has been configured with a phased antenna array formed by a plurality of antennas. As shown in FIG. 3, each corner has an array formed by three respective antenna 40, oriented to 0 degrees, 45 degrees, and 90 degrees. The adjacent antenna has a radiation diagram that is oriented in a direction separated from 45 degrees, and an antenna array at each corner may have any suitable number of antennas (eg, two or more, three or more, three Top 5, three to eight, less than five, less than ten, etc.), and these antennas can pass any suitable angular quantity (0-45 degrees, 10-30 more than 5 degrees, less than 25 degrees , Less than 75 degrees, etc.) radiate outward.
In addition to using in future IDEvices and Macs, Apple pointers that new antennas may also be applied to other possible future devices, such as embedding in glasses or other user header devices, or other wearable micro devices, televisions, Computer displays, game devices, navigation devices, and embedded systems such as electronic devices such as embedded monitors such as in the kiosk or car. Considering this is a patent application, the timing of such products is still unknown, although the 5G network may be implemented in the next few years.
