[0017] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples.
[0018] As Figs. 1 to 3As shown, the utility model discloses a 5G dual -port high -gain directional antenna, including PCB board 1, first radio frequency line 2, second radio frequency line 3, first jumper 4, second jumper 5, the front of PCB board 1 is equipped with a pair of horizontal arrangement's first antenna oscillator 6, the back of PCB board 1 is equipped with a pair of vertical parallel arrangement's second antenna oscillator 7, first jumper 4 is connected in series with the center feed point of a pair of first antenna oscillator 6, first radio frequency line 2 is connected with the center feed point of one of first antenna oscillator 6, second jumper 5 is connected in series with the center feed point of a pair of second antenna oscillator 7, second radio frequency line 3 is connected with the center feed point of one of second antenna oscillator 7, the center feed point of first antenna oscillator 6 and the center feed point of second antenna oscillator 7 are mutually crossed and staggered on the front of PCB board 1.
[0019] PCB board 1 can adopt FR4 board. PCB board 1 adopts the structure design that both sides have circuit, and a pair of first antenna oscillator 6 arranged horizontally on the front forms horizontal polarization of the antenna, and a pair of second antenna oscillator 7 arranged vertically on the back forms vertical polarization of the antenna, and the antenna oscillator on the front and back is connected in series through jumper respectively, and the antenna oscillator on the front and back is connected with corresponding radio frequency line respectively, and the antenna oscillator is centrally fed, and horizontal and vertical connection is separated, and forms two radio frequency ports on the front and back. The center feed point of first antenna oscillator 6 and the center feed point of second antenna oscillator 7 are mutually staggered, which can avoid the cross influence caused by overlapping on the front and back feed.
[0020] Each first antenna oscillator 6 is formed by two symmetrically coupled first radiators 61, one end of each first radiator 61 is provided with a first feed point 62, the first feed points 62 of the two first radiators 61 are opposite, and the two first radiators 61 are arranged opposite along the horizontal direction of the PCB board 1.
[0021] The first radiators 61 gradually converge towards the first feed points 62. The convergence structure can be a symmetrical chamfer structure formed near the first feed points 62 of the first radiators 61. The convergence structure of the first radiators 61 ensures the radiation effect of the front and back respectively without overlapping with the second radiators 71.
[0022] The pair of first antenna oscillators 6 are distributed side by side along the horizontal direction of the front of the PCB board 1. The four first radiators 61 are side by side in the horizontal direction of the PCB board 1, and each two first radiators 61 are symmetrically coupled, forming two first radiators 61 arranged opposite along the horizontal direction of the PCB board 1, and horizontal polarization of the antenna is formed by symmetric coupling.
[0023] One end of the first jumper 4 is connected to two first feed points 62 of one of the first antenna elements 6, and the other end of the first jumper 4 is connected to one first feed point 62 of the other first antenna element 6. The first radio frequency (RF) line 2 is connected to the other first feed point 62 of the other first antenna element 6, and the first RF line 2 is connected in series with the first jumper 4 through a feed element 8. The first RF line 2, through the series connection of the first jumper 4, provides feed connection for the two horizontally polarized first antenna elements 6, forming a horizontally polarized feed port. The feed element 8 serves as a transition conductor connecting the first RF line 2 and the first jumper 4 in series.
[0024] Each second antenna oscillator 7 is composed of two symmetrically coupled second radiators 71. Each second radiator 71 has a second feed point 72 at one end. The second feed points 72 of the two second radiators 71 are opposite to each other, and the two second radiators 71 are arranged opposite each other along the vertical direction of the PCB board 1.
[0025] The second radiator 71 gradually converges towards the second feed point 72. The convergence structure can be a symmetrical chamfered structure formed at the position of the second radiator 71 near the second feed point 72. The convergence structure of the second radiator 71 is designed to prevent it from overlapping with the first radiator 61, thereby ensuring the radiation effect of each side.
[0026] A pair of second antenna elements 7 are arranged side-by-side along the horizontal direction of the reverse side of the PCB board 1. Each pair of second radiators 71 is symmetrically coupled in the vertical direction, forming two second radiators 71 arranged opposite each other along the vertical direction of the PCB board 1. This symmetrical coupling creates the vertical polarization of the antenna. The horizontal distribution of the pair of second antenna elements 7 makes full use of the horizontal space of the PCB board 1 and corresponds to the position of the first antenna element 6, forming a mutually intersecting and staggered spatial structure.
[0027] One end of the second jumper 5 is connected to two second feed points 72 of one of the second antenna elements 7, and the other end of the second jumper 5 is connected to one second feed point 72 of the other second antenna element 7. The second RF line 3 is connected to the other second feed point 72 of the other second antenna element 7, and the second RF line 3 is connected in series with the second jumper 5 through the feed element 8. The second RF line 3, through the series connection of the second jumper 5, provides feed connection for the two vertically polarized second antenna elements 7, forming a vertically polarized feed port. The feed element 8 serves as a transition conductor connecting the second RF line 3 and the second jumper 5 in series.
[0028] The 5G double-port high-gain directional antenna has lines on the front and back surfaces, one horizontal polarization and one vertical polarization, the antenna oscillators are connected in series by radio frequency lines, and the antenna oscillators are symmetrically coupled to achieve wide frequency and correct directional diagram. In this way, the isolation problem between the two antennas is solved. The antenna uses conventional PCB and radio frequency cable to achieve 3300MHz-5GHz, and ordinary FR4 board can also meet the high gain requirement. The gain of this type of antenna is high, the radiation directional diagram is not biased and relatively correct, the antenna isolation is high, and the port is multiple.
