In another alternative embodiment, it may be determined whether each of the alternative operating frequencies has at least one multiplied frequency within the current operating frequency range of the antenna, and if so, a new operating frequency is determined from the alternative operating frequencies of the even or odd multiplied frequencies within the current operating frequency range of the antenna.
Wherein, the even-order frequency doubling frequency is the frequency doubling frequency calculated by the even-number when the frequency doubling frequency is calculated, the odd-order frequency doubling frequency is the frequency doubling frequency calculated by the odd-number when the frequency doubling frequency is calculated, exemplarily, the current working frequency of the camera a is 300MHz, and the 3-fold frequency doubling frequency of the current working frequency 300MHz is within the current working frequency range 800-1400MHz of the antenna a, it can be determined that the alternative working frequencies 400MHz, 500MHz, 600MHz, 700MHz all have frequency doubling frequencies within the current working frequency range 800-2500MHz of the antenna a, wherein the alternative working frequencies of the 2-fold frequency doubling frequency within the current working frequency range 800-1400MHz of the antenna a have 400MHz, 500MHz, 600MHz, 700MHz, and the alternative working frequencies of the 3-fold frequency doubling frequency within the current working frequency range 800-1400MHz of the antenna a have 400MHz, if the antenna a is sensitive to the even-order frequency, the alternative working frequency 400MHz of odd-order frequency multiplication frequency within the current working frequency range of 800-.
In another optional embodiment, a new operating frequency of the interference source may be found in a preset frequency table, where a frequency multiplication frequency of the new operating frequency is outside an operating frequency range of the antenna, and in the frequency table, it may be found that frequency multiplication frequencies of the alternative operating frequencies 600MHz and 700MHz are not within the operating frequency range of the antenna a, 800-.
And S208, controlling the interference source to work at a new working frequency.
After the new operating frequency is determined, the new operating frequency can be set as the operating frequency of the interference source, and the interference source does not generate interference on the antenna after operating at the new operating frequency.
After the current working frequency range of the antenna, the working frequency range of the interference source and the current working frequency of the interference source are obtained, a plurality of frequency doubling frequencies are calculated by taking the working frequency of the interference source as a base frequency, whether at least one frequency doubling frequency is in the current working frequency range of the antenna is judged, if yes, a plurality of alternative working frequencies are determined in the working frequency range of the interference source, each alternative working frequency is taken as the base frequency, a plurality of frequency doubling frequencies of the alternative working frequency are calculated, a new working frequency is determined from the plurality of alternative working frequencies, and the interference source is adjusted to work at the new working frequency when the plurality of frequency doubling frequencies of the new working frequency are out of the current working frequency range of the antenna. Therefore, the working frequency and the frequency multiplication frequency of the interference source are not coincident with the current working frequency of the antenna, the interference source cannot interfere with the antenna, a metal shielding cover is not needed to shield the antenna, the antenna is not interfered by the interference source, the sensitivity is improved, and the manufacturing cost is reduced.
Furthermore, whether the frequency multiplication frequency of the current working frequency of the interference source is within the current working frequency range of the antenna can be judged by looking up a preset frequency table, and the new working frequency can be determined by looking up the table, so that whether the interference source generates interference on the antenna can be conveniently and quickly judged, the new working frequency can be quickly and conveniently obtained, and the efficiency of adjusting the working frequency of the interference source is improved.
Furthermore, when at least one frequency multiplication frequency exists in all the alternative working frequencies of the interference source and is in the current working frequency range of the antenna, a new working frequency is determined from the alternative working frequencies of the even-order or odd-order frequency multiplication frequency in the current working frequency range of the antenna, so that when the frequency multiplication frequencies of all the alternative working frequencies of the interference source are in the current working frequency range of the antenna, the alternative working frequency with smaller interference is selected as the new working frequency, and the interference of the interference source on the antenna is reduced.
