Don't twist the FPC antenna?
FPC antenna has a certain degree of flexibility and can be bent within a certain range, but it cannot be bent arbitrarily. Excessive or improper bending may affect the performance of the antenna and even damage it. Here are some precautions regarding FPC antenna bending:
1. Consequences of bending
Antenna damage: Excessive bending may cause circuit board breakage or line breakage.
Performance degradation: Excessive bending may alter the electrical characteristics of the antenna (such as impedance matching, radiation patterns, etc.), leading to signal attenuation, frequency offset, and other issues.
2. The impact of bending on performance
Impedance matching: Bending may affect the impedance distribution of the antenna, resulting in increased signal reflection and reduced transmission efficiency.
Standing Wave Ratio (VSWR): Excessive bending of the antenna may result in an increase in VSWR, reducing the quality of communication.
Bandwidth and frequency characteristics: The frequency response and bandwidth of FPC antennas may be affected by bending, especially in high-frequency applications such as Wi Fi, Bluetooth, etc.
3. Other precautions
Bending during long-term use: If the antenna is frequently bent during long-term use, it may cause material fatigue, thereby affecting the long-term stability of the antenna. Therefore, in practical applications, it is necessary to consider the bending life of the antenna.
Temperature changes: FPC antennas may be affected by temperature changes, especially at high temperatures, where the material may expand or contract, affecting the stability of bending and the quality of signal transmission.
Summary
FPC antennas can be bent within a certain range, but should not be excessively bent. The bending radius should follow the manufacturer's specifications to avoid affecting the performance of the antenna and causing damage. In practical use, it is important to ensure that the antenna operates within a reasonable bending range and avoid sharp folding or excessive bending.
