Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0045] It should be noted that if there are directional indications such as up, down, left, right, front, back, etc. in the embodiment of the present invention, the directional indications are only used to explain the position of each individual in a certain posture as shown in the attached figure. If the relative positional relationship, movement conditions, etc. between the components change, the directional indication will also change accordingly. ...

The invention discloses an antenna oscillator and a broadband multi-port omnidirectional antenna using the same. The oscillator comprises an oscillator main body, the oscillator main body is formed bysplicing a rectangular part and a trapezoidal part, one side of the rectangular part is fixedly connected with one side of the trapezoidal part, a plurality of parallel through grooves are formed inthe rectangular part, and a groove is formed in one side, far away from the rectangular part, of the trapezoidal part. A fish-shaped structure is formed by the rectangular part, the trapezoidal part,the through groove and the groove; the special fish-shaped structure is arranged for impedance matching, a directional diagram and gain are considered, the frequency band width is expanded, the bandwidth of the oscillator main body can be specifically expanded to the range of 600-6000 MHz, the overall size of the oscillator main body is small, multiple oscillator main bodies can be conveniently arrayed, and the capacity of the antenna is expanded. Due to the special position relation between the isolation sheets and the fish-shaped oscillator main bodies, the interference among the oscillatormain bodies is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna vibrator and a broadband multi-port omnidirectional antenna using the same. Background technique [0002] Omnidirectional antennas, that is, 360° uniform radiation on the horizontal pattern, which is commonly referred to as non-directional, and a beam with a certain width on the vertical pattern, generally the smaller the lobe width, The greater the gain. [0003] Traditional omni-directional antennas for indoor signal coverage, the structure of the main body of the vibrator is mainly conical, and the overall volume is relatively large. When multiple conical vibrators are arrayed, the volume is further expanded, making the antenna The overall volume of the antenna has become very large, and a large space needs to be reserved for the installation of the antenna. It is inconvenient to use when the space is small, which limits the usage scenarios of the antenna; and the...
