Description
Technical field
The utility model relates to a kind of antenna, particularly relates to a kind of high-isolation mimo antenna that can be used for WIMAX.
Background technology
Along with the extensive use of Wireless Telecom Equipment, advantages such as inverse-F antenna is because having bandwidth, and volume is little, and section is low and become Wireless Telecom Equipment and adopt more a kind of built-in antenna.
Worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, WIMAX) be an emerging wireless access wide band technology, this technology is based on IEEE802.16 standard, the high speed of Internet can be provided to connect, and current WIMAX operates mainly in 2.50-2.69GHz, 3.40-3.69GHz and 5.25-5.85GHz frequency range.
MIMO represents MIMO technique, it uses multiple transmitting antenna and reception antenna respectively at transmitting terminal and receiving terminal, signal is undertaken transmitting and receiving by multiple antennas of transmitting terminal and receiving terminal, thus takes full advantage of space resources, improves communication quality.
For the mimo antenna being applied to WIMAX field, require the feature with low-loss, high-isolation, simultaneously, along with Wireless Telecom Equipment more and more develops to miniaturization, therefore the design for the wireless device terminal antenna being applied to WIMAX field it is also proposed the requirements such as miniaturization, low-loss, high-isolation, but common mimo antenna exists low, the bulky shortcoming of isolation.
Therefore, the structure changing mimo antenna makes it fully meet the requirements such as miniaturization, low-loss and high-isolation just becomes the key issue that must solve.
Summary of the invention
In order to solve low, the bulky deficiency of existing mimo antenna isolation, the utility model provides a kind of high-isolation mimo antenna that can be used for WIMAX, and this antenna not only isolation is high, and its volume is little, is applicable to miniaturized Wireless Telecom Equipment.
The utility model solves the technical scheme that its technical problem adopts: a kind of high-isolation mimo antenna that can be used for WIMAX, comprise a medium substrate, two antenna radiation units, two feed port and two substrate metal ground, the upper surface of described medium substrate and lower surface are all coated with substrate metal ground, described two antenna radiation units all fit in the region on non-covered substrate metal ground in the upper surface of medium substrate, and described two antenna radiation units are spatially vertically placed in 90 degree, described two antenna radiation units all with the substrate metal of medium substrate upper surface be connected.
The beneficial effects of the utility model are: can become a kind of antenna being applied to WIMAX field Wireless Telecom Equipment, have that high-isolation, volume are little, the simple feature of structure.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the high-isolation mimo antenna of a kind of WIMAX of can be used for described in the utility model forms by with lower component: medium substrate 1, antenna radiation unit 2, feed port 3, substrate metal ground 4, wherein the upper surface of medium substrate 1 and lower surface are all coated with substrate metal ground 4, when carrying out feed to antenna, the outer conductor of coaxial line is connected with substrate metal ground 4, the inner wire of coaxial line is connected with feed port 3, two antenna radiation unit 2 shapes are identical and all fit in the region on non-covered substrate metal ground 4 in the upper surface of medium substrate 1, two antenna radiation units 2 are spatially vertically placed in 90 degree, two antenna radiation units 2 are all connected with the substrate metal ground 4 of medium substrate 1 upper surface.
With reference to Fig. 2 and Fig. 3, medium substrate 1 can use common FR4 material to make, and thickness is 0.8mm, length is 90mm, and width is 40mm, and antenna radiation unit 2 is copper product with substrate metal ground 4 and makes, specific implementation on medium substrate 1, can be made by typography.
The simulation curve figure of the S parameter of antenna when feed port 3 feed is given with reference to Fig. 4, the working frequency range of two antenna radiation units 2 is respectively 2.49-2.73GHz, 2.51-2.69GHz as can see from Figure 4, and the isolation of antenna in 2.49-2.73GHz frequency range is lower than-18.92dB.
Give the simulation curve figure of the standing-wave ratio coefficient of antenna when feed port 3 feed with reference to Fig. 5, standing-wave ratio coefficient VSWR1, VSWR2 of antenna are all less than 2.0:1 in 2.49-2.73GHz frequency range as can see from Figure 5.
