Three-frequency-band antenna assembly and fiber-to-room access equipment

The embodiment of the utility model discloses a three-frequency-band antenna assembly and fiber-to-room access equipment, and relates to the technical field of antennas. According to the specific scheme, the three-frequency-band antenna assembly comprises a substrate, an isolation piece, a first dipole antenna, a second dipole antenna and a first antenna. The first dipole antenna and the second dipole antenna share one gap. And the first dipole antenna and the second dipole antenna share one feeder line. The vertical projection of the separator on the substrate is located between the gap and the first antenna. The isolation piece comprises a U-shaped piece and an L-shaped piece. The three-frequency-band antenna assembly integrates antennas of three frequency bands, is high in integration level, and can cover each frequency band of a WLAN, thereby improving the use bandwidth and adaptation performance of the three-frequency-band antenna assembly. The method can be used in an FTTR scene.
