IPhone 13 antenna is made of plastic bottles. Can the signal work?

The signal antenna of iPhone 13 is actually made of plastic bottles. Yes, that's the bottle of mineral water we usually drink. As we all know, the signal problem of Apple's mobile phone has always been a serious injury. In recent years, the iPhone went blind as soon as it arrived in the garage, which is worse than mainstream domestic mobile phones such as Huawei. This time, iPhone 13 uses plastic as antenna. What's going on here? First of all, from the introduction of Apple official website's iPhone 13, we can see that iPhone 13 is the first mobile phone brand in the industry to transform plastic bottles into high-performance materials to make mobile phone antennas. Although you have to admire Apple's determination to protect the environment, it's hard to say whether it's really environmental protection or fake environmental protection, but you will definitely worry about the mobile phone antenna made of plastic bottles. Alas, before discussing this issue, let's first understand the mainstream FPC antenna and LDS antenna in mobile phones, which are two kinds of built-in antennas.

Among them, FPC antenna is generally drawn on PCB and made of other external metals. Usually used in complex frequency bands, low-end mobile phones and intelligent hardware products. The advantages are that it is suitable for almost all small electronic products, can be used as a composite antenna with more than ten frequency bands, and has good performance and relatively low cost. The disadvantage is that it needs to be debugged according to each product. The other is LDS antenna, which is an evolved version of FPC antenna. The space utilization rate is extremely high. FPC antenna is stamped and must be flat and not too complicated. LDS antenna engraves the antenna pattern by laser, which is very suitable for products with compact internal space. Its advantage is that it can make full use of various irregular surfaces in three-dimensional space and reduce the antenna volume. But the disadvantage is that it is more expensive, one order of magnitude more expensive than FPC antenna.

At present, LDS technology is widely used in the field of 5G mobile phones, especially high-end flagship mobile phones, such as Huawei P40 and Mate40 series. With the outbreak of 5G network, the advantages of LDS antenna technology are highlighted, which makes the signal reception of mobile phones more stable. However, it is hard to say whether the signal of iPhone 13 has improved this time. From a technical point of view, it shouldn't be bad, so don't worry if you buy a new iPhone. Anyway, its signal is already very poor, and it can't be worse. At most, there is no signal from time to time, forcing you to put down your mobile phone and have a rest. You see, how humanized apples are, don't you think?
