  • mode 1 the performance of mode 1 is the worst, and it is also the most complained by the user. The reason is that in the head-hand mode, the antenna will have a frequency offset and a mismatch, resulting in a significant drop in antenna performance.
  • Antenna Tuning Architecture When passive antennas no longer meet the performance requirements of increased bandwidth requirements, more complex handset designs, and smaller available antenna space, open-loop antenna tuning systems are often used.
  • the tunable component fine-tunes the performance of the antenna in a set frequency band and operating mode based on static information (such as transmit/receive frequency, modulation scheme, or usage).
  • static information such as transmit/receive frequency, modulation scheme, or usage.
  • the open loop system does not measure the operating conditions of the antenna in real time, it is not possible to specifically consider the environmental conditions.
  • the mismatch sensing unit tracks the health of the antenna and provides a feedback signal that reflects the actual situation.
  • the mismatch sensing unit compares the VSWR (the power amplitude reflected back to the antenna) with the transmit power and adjusts the impedance tuning circuit.
  • the tuning algorithm allows the tunable component to continuously track environmental conditions under various conditions of use and adjust the impedance to an optimum value.

  • BST barium titanate
  • Antennas are complex devices, and antennas embedded in cell phones are no exception. Since the RF transceiver of the mobile phone is designed for 50 ⁇ impedance, its antenna is also preferably 50 ⁇ impedance across the entire frequency band. But in fact, this is rarely done, because according to the law of electromagnetics, mobile phones are inherently characterized by narrow antenna bandwidth, poor matching and low radiation efficiency. Thus, the antenna is typically designed for non-50 ⁇ impedance throughout the band, and for multi-band antennas, the typical value for VSWR is 2:1 or 3:1. Antenna impedance is also affected by other factors, such as the way the phone is held (ie, the "head hand effect"). The user's body also absorbs power, further limiting the radiation efficiency of the antenna.
  • FIG. 1 shows the effect of the "head hand effect", which refers to the antenna's detuning when the hand is placed near the antenna transmitter. This effect changes the resonant frequency of the antenna, causing the antenna to be heavily mismatched at the predetermined operating frequency. When the user places his hand near the antenna transmitter, the resonant frequency of the antenna changes, resulting in a mismatch at the predetermined operating frequency.
  • Adaptive antenna tuning is expected to be a good way to meet these new TRP and TIS specifications.
  • the antenna tuner can be 50 ⁇ independent of the environment and allow the rest of the system to operate under optimal conditions. Although the antenna tuner introduces some additional insertion loss, adaptive antenna tuning will greatly reduce the total insertion loss from the tuner input to the antenna input, which improves performance, compared to the case where no antenna tuner is added.
  • Antennas for multi-band transceiver systems require an adaptive antenna tuning circuit that guarantees performance over the entire band up to the band edge, actively tracking the resonance point offset and quickly retuning the antenna's resonance point.
  • This tuned circuit must have extremely high linearity to avoid harmonics or intermodulation distortion. It should also be small and durable.
  • the tuning ratio should be at least 3:1 and the power consumption of the entire circuit should be less than 1mA. In order to effectively improve performance, the insertion loss of the circuit must be small, so the quality factor (Q) should be at least 50.

  • the following technical solutions are still used to solve the problem of the hand mode call: 1.

  • the hand mode is dominant, and the free space performance is sacrificed; 3. Focus on free space and take care of the head hand model.
