5G has more antennas. Are you worried about how to design them? The main way to solve the problems caused by the reduction of antenna area and reduced efficiency in mobile phones is to use aperture tuning. It is crucial to enable smartphones to support an ever-expanding range of frequency bands, especially in the transition to 5G. Aperture tuning has a significant impact on the efficiency of antennas for transmitting and receiving communications. Depending on the application, the total radiated power (TRP) and total isotropic sensitivity (TIS) can be improved by up to 3dB or more. Antenna aperture tuning is critical for smartphones to ensure that they can operate effectively in an ever-increasing range of RF frequency bands and support the transition to 5G.
The concept of antenna tuning technology is shown in Figure 4. A switch connected between the antenna and ground is used to adjust the resonant frequency of the antenna to match the frequency that the phone is currently using to communicate.
Adding different tuning components (capacitors or inductors) between the switch and the radiating element can be used to further adjust the resonant frequency to support different frequency bands. Figure 4 shows the resonant frequency of the antenna when the switch is open, open, and when an inductor or capacitor is added to the circuit.
In Figure 4, each component is connected to a simple switch to illustrate the concept of aperture tuning. However, in main wireless communication antennas and some other applications, more complex multi-throw switches can be used to connect multiple tuning components and support a wider range of frequency bands.
It takes a lot of experience to achieve your goals with aperture tuning technology. Are you ready? Here is a practical guide to aperture tuning: an essential technology in 5G smartphones . Friends who are engaged in 5G development can take a look at this to help you lead the industry in product development.
