High-different frequency isolation broadband double-frequency base station antenna array

The invention discloses a high-different frequency isolation broadband double-frequency base station antenna array, which comprises at least one high-frequency antenna unit, a low-frequency antenna unit and a floor board, wherein when one high-frequency antenna unit exists, the high-frequency antenna unit is placed at one side of the floor board, when multiple high-frequency antenna units exist, the high-frequency antenna units are placed at two sides of the floor board respectively, each high-frequency antenna unit comprises multiple oscillator arms and a Balun, the oscillator arms are connected through a distributed inductor, and feeding is carried out through the Balun; the low-frequency antenna unit is placed in the middle of the floor board and comprises multiple oscillator arms and a Balun, the oscillator arms are connected through a distributed capacitor, feeding is carried out through the Balun, the Balun is provided with a feeder line and an H-type microstrip branch, and the H-type microstrip branch is connected with the feeder line. In a condition of not cascading filters, high isolation in a condition in which the distance between the different-frequency antenna units is small and the floor board is small can be realized, insertion loss of a filter is avoided, a stable pattern in a broadband is realized, and due to a decoupling structure, the volume of an antenna unit is not added extraly.

Antenna assembly and electronic equipment

The invention provides an antenna assembly and electronic equipment. The antenna assembly comprises a first antenna and a second antenna; the first antenna comprises a first radiator, a first signal source and a first frequency-selecting filter circuit; the second antenna comprises a second radiator, a second signal source and a second frequency-selecting filter circuit, and the first radiator andthe second radiator are arranged at intervals and coupled with each other; the first signal source is electrically connected with the first frequency-selecting filter circuit to the first radiator, the second signal source is electrically connected with the second frequency-selecting filter circuit to the second radiator, the first antenna is used for generating at least one resonance mode, and the second antenna is used for generating at least two resonance modes; at least two resonance modes of the second antenna are used for transmitting and receiving electromagnetic wave signals coveringa first frequency band, a second frequency band and a third frequency band, and at least one resonance mode of the second antenna is generated by capacitive coupling feed excitation between the firstantenna and the second antenna. The antenna assembly provided by the invention has a relatively good communication effect.
