1. A antenna, comprising:
a low-frequency antenna, comprising an antenna having a working band lower than 6 GHz;
a high-frequency antenna, comprising an array antenna that works at a millimeter wave band, wherein the low-frequency antenna and the high-frequency antenna are fed by the same feeding point; and
a low-pass filter arranged between the low-frequency antenna and the high-frequency antenna for isolating the low-frequency antenna and the high-frequency antenna,
wherein the low-pass filter comprises at least one open circuit, and in a case where power supply comprises both high-frequency signals and low-frequency signals and when the high-frequency antenna works, the low-pass filter serves as an open circuit so as to prevent the power supply to the low-frequency antenna.
