Triangular prism eight port PHS base station antenna

The utility model discloses a triangular prism eight port PHS base station antenna. The utility model integrates three sector omnidirectional coverage dual polarization and a directional sector dual polarized antenna into a whole, and has the function of sector space dual diversity. The utility model is characterized in that the dual polarized unit of the trihedral antenna is divided into an upper group and a lower group according to the gain balance principle; each of polarization vibrators with the same degree of the upper group of the three sector antenna dual polarization unit is connected with a three-way power synthesizer and carries out power synthesis, so that two omnidirectional antennae and two omnidirectional coverage beam interfaces are formed; each polarization vibrator of the lower group of a three sector antenna dual polarized antenna radiating unit is connected with a feeding network, so that six directional sector antennae and six directional beam direct output interfaces which cover different areas are formed; eight radio frequency ports in all can be in matching connection with PHS enhanced C7T base stations. The utility model can have dual polarization or four polarization, the signal to jamming ratio of the utility model is improved and the gain of the utility model is greater than 11 decibels. The utility model can be used for PHS base stations, GSM or CDMA mobile base stations and other communication systems.
