In fig. 1, when the first body 10 and the second body 20 are middle frames of the electronic device 100, a radiator such as the first antenna 101 may be formed by forming a slot in the middle frame so that the electronic device 100 has a communication function, and thus the electronic device 100 may radiate and receive radio waves using the antenna.

In the present application, the location of the connection point of the first switch assembly 202 is related to the location of the first spurious signal generation. Meanwhile, the position of the second camera 602, the position of the first electroacoustic device 702, the size and the position of the antenna slot, and other hardware parameters are also related to the frequency band corresponding to the first electromagnetic wave signal. It can be understood that the hardware parameters and the frequency band of the first electromagnetic wave signal have an influence on the frequency and amplitude of the first noise generated by the folding. Therefore, the position of the first switch element 202 is determined based on the hardware parameters and the frequency band of the first electromagnetic wave signal, which facilitates to improve the noise canceling capability of the first switch element 202.
The length h of the antenna is theoretically 1/4 wavelengths or 1/2 wavelengths, which maximizes efficiency. This length h refers to the actual length of the antenna we see, for which there is actually also a parameter of the electrical length heElectric length heNot only with respect to the actual length of the antenna, but also with respect to the frequency of the signal radiated by the antenna, when the length of the antenna is of the order of magnitudeElectrical length of timeWhen the length of the antennaElectrical length of timeWherein the content of the first and second substances,
we will often see that the electrical length of the antenna or the effective electrical length of the antenna is the signal wavelength/pi, which is actually calculated by the above formula by default that the actual physical length of the antenna is equal to 1/2 wavelength, and then for signals of different frequencies, the wavelengths are different, so that they are not necessarily 1/2 of the actual physical length of the antenna, so the electrical length is not always the wavelength/pi. The accurate calculation of the effective electrical length of the antenna for signals of different frequencies needs to be calculated by the above formula.
Electrical length matching means that the required electrical length is adapted to the electrical length of the radiator used for exciting the electromagnetic wave signal, and this operating state is called matching, otherwise called mismatch. If the electrical length of the first metal piece is mismatched with the electrical length required by radiation of the first clutter signal, the interference of the first clutter signal on the first electromagnetic wave signal can be eliminated, and the communication quality is improved.
It can be understood that, after the first body 10 and the second body 20 are folded, the distance between the first metal part 201 and the first antenna 101 is less than a preset distance, which may be, but not limited to, 5mm, at this time, the distance between the first metal part 201 and the first antenna 101 is very close, the first metal part 201 couples the first electromagnetic wave signal generated by the first antenna, so as to generate a first clutter signal, and after the first metal part 201 is grounded through the first switch assembly 202, the electrical length of the first metal part 201 may be adjusted through the first switch assembly 202, so that the electrical length of the first metal part 201 is mismatched with the electrical length required for radiating the first clutter signal, or the frequency band range of the first clutter signal is different from the frequency band range of the first electromagnetic wave signal. Therefore, the first switch module 202 filters the first clutter signal generated by the first antenna 101, so as to eliminate the clutter interference corresponding to the first antenna 101, thereby improving the communication quality.
