Example Embodiment

[0056] Example one:

[0057] See figure 1 The antenna provided by the first embodiment of the present invention includes a radiator 1, a director 2, one or two wave absorbers 3, and a reflector 4. The director 2 is located at the radiator 1 relative to the radiation direction of the radiator 1. In the front, the reflector 4 is located behind the radiator 1, and two wave absorbers 3 are located on the two sides of the radiator 1 respectively.

[0058] The antenna provided in the first embodiment of the present invention may also include one or two isolators 5, and the two isolators 5 are respectively located behind the two wave absorbers 3 facing away from the radiator 1, or located at the back of the two wave absorbers 3 facing the radiation. The front of the device 1. The isolator 5 can use I-shaped single negative dielectric constant material (such as figure 2 Shown). The reflector 4 in the antenna provided in the first embodiment of the present invention may be a flat metal ...

Example Embodiment

[0090] Embodiment two:

[0091] See Figure 15 The difference between the antenna provided in the second embodiment of the present invention and the antenna provided in the first embodiment of the present invention lies in the use of a director 6 of another structure and a reflector 7 of another structure.

[0092] See Figure 16 to Figure 22 The antenna director provided by the second embodiment of the present invention working in the 5.8 GHz frequency band includes a zero refractive index lens 51 and one or two FSS lenses 52 in the antenna director provided by the first embodiment of the present invention. The period of the resonant screen unit structure of the FSS lens 52 and the periods of the capacitive metal patches of the first capacitive screen and the second capacitive screen in the second embodiment of the present invention can be compared with those of the first embodiment of the present invention working in the 2.4 GHz frequency band. The period of the FSS lens is les...

Abstract

The invention is applicable to the field of communication, and provides an antenna and a wireless router. The antenna comprises a radiator, a director, at least one wave absorber and a reflector, wherein relative to the radiation direction of the radiator, the director is in front of the radiator, the reflector is behind the radiator, and the wave absorber is located on a side face of the radiator; and the radiator comprises a base plate, a composite left and right hand transmission line unit attached to a front face of the base plate, an electromagnetic field band gap EBG structure attached to a bottom face of the base plate, and a flat metal plate located on the side of the EBG structure and connected with the composite left and right hand transmission line unit to serve as the ground. The antenna provided by the invention has the advantages of small size, low profile, horizontal omnidirectional radiation, high efficiency and wide bandwidth.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an antenna and a wireless router. Background technique [0002] Antennas in the prior art include radiators, reflectors, directors, isolation elements, and the like. Among them, the radiator mainly uses dipoles or monopoles to provide horizontal omnidirectional and vertically polarized radiation performance. Dipoles or monopoles are radiations whose electrical length is 1 / 2 or 1 / 4 of the wavelength of the antenna. The radiation is omnidirectional on the horizontal plane, and the polarization direction of the radiated electric field is perpendicular to the earth, that is, vertical polarization. When this type of radiator is used, it is generally placed outside the antenna perpendicular to the horizontal plane. However, the radiator has narrow bandwidth, low radiation efficiency, high profile and cannot be planarized, so that the antenna in the prior art has large size, narro...
