Embodiment Construction
[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] see figure 1 and figure 2 , the double-sided dipole antenna applied to the network communication terminal equipment in the preferred embodiment of the present invention, instead of the middle feeding mode of the previous dipole antenna, adopts side feeding, so as to be suitable for complex antenna application environments. The main body of the antenna is printed on the PCB, which can be made into a PCB antenna alone, or printed on the system motherboard to make an on-board antenna.
[0021] The substrate includes a first surface 1 and a second surface 2 o...

The present invention provides a double-sided dipole antenna. The antenna includes a first antenna unit and a second antenna unit. The first antenna unit includes: a first main radiation part; a first ground radiation part; a first signal A transmission part, one end of which is coupled to the end of the first main radiating part opposite to the first ground radiating part, and the other end is provided with a signal feeding point; and a first grounding point; the second antenna unit includes: The second ground radiation part is arranged opposite to the first ground radiation part and conductively connected to form a current balance; and the second signal transmission part has one end coupled to one end of the second ground radiation part and the other end coupled to at the second ground point. The special feed through the parallel double-guided signal feed section enables it to be used in a very narrow hardware environment; the main radiation part and the ground radiation part are simple and easy to adjust, and can be applied to various required frequency bands; two grounds The pass-through of the radiating part is connected to a conductive, protective ground current.
Description
technical field [0001] The invention relates to antenna technology, in particular to a double-sided dipole antenna. Background technique [0002] As people's requirements for communication quality and integration of communication equipment continue to increase. As a sub-component of communication equipment, antennas also require higher performance to meet the needs of communication systems. The penetration rate of various mobile terminal devices in the society is increasing very fast. Among them, the most convenient and fastest way is the wireless access method, because the wireless access method saves a lot of network laying costs and can be quickly planned. , Quick installation, quick put into use, and relatively simple maintenance. How to design a miniaturized built-in antenna has become a difficulty and bottleneck in the development of mobile communications. Therefore, in order to meet the characteristics of this product, the corresponding built-in antenna needs to be ...
