The utility model discloses a simple, workable, the just easy and microwave circuit integration of antenna structure can be applied to among the WLANWiMAX communication system.
Description
Technical field
The application belongs to wireless communication technology field, particularly relates to a kind of three radio-frequency radiation flat plane antennas.
Background technology
Wireless domain is worked out for the different market demands and application model different standards, as being applied to the IEEE802.16 standard of WLAN, also known as micro-wave access global inter communication (WorldInteroperabilityforMicrowaveAccess, WiMAX).Wherein, the mobile WiMAX in IEEE802.16e comprises 2.3GHz and 2.7GHz frequency range.
In recent years, the requirement of wireless communication system to antenna is more and more higher, and the microstrip antenna of advantages such as having thin profile, volume is little, quality is little, be easy of integration obtains research and apply widely.Meanwhile, often require that multiple working frequency range coexists in modern wireless communication systems, the wireless communication system working in double frequency or multiband is an important directions of development at present.
