Abstract
A double-frequency microstrip antenna disclosed by the present invention comprises a dielectric plate, a metal grounding plate formed on one surface of the dielectric plate, and a microstrip feeder line formed on the other surface of the dielectric plate. The metal grounding plate is equipped with a first circular ring slit and a second circular ring slit which are arranged concentrically, and four first rectangular slits are connected between the first and second circular ring slits and are in equal spacing annular array distribution. The double-frequency microstrip antenna of the present invention realizes the two high and low frequency bands by the two circular ring slits, enables the energy to be coupled from an outer circular ring to an inner circular ring by the four rectangular slits connected between the two circular ring slits, and enables the frequency characteristic of the low frequency band and the bandwidth to be improved by the second and third rectangular slits.

Technical field
The application belongs to wireless communication technology field, particularly relates to a kind of double-frequency micro-strip antenna.
Background technology
Wireless domain is worked out for the different market demands and application model has different standards, as being applied to
IEEE 802.16 standard of WLAN, also known as micro-wave access global inter communication (World
Interoperability for MicrowaveAccess, WiMAX).Wherein, the shifting in IEEE 802.16e
Dynamic WiMAX includes 2.3GHz and 2.7GHz frequency range.
In recent years, wireless communication system is more and more higher to the requirement of antenna, have thin profile, volume little,
The microstrip antenna of the advantages such as quality is little, easy of integration has obtained studying widely and applying.Meanwhile, modern nothing
Line communication system often requiring that, multiple working frequency range coexists, and works in the channel radio of double frequency or multiband
Communication system is an important directions of development at present.

It is distributed away from annular array.
Preferably, in above-mentioned double-frequency micro-strip antenna, the diameter of described first annular slot is less than described
The diameter of the second annular slot, be provided with in the circular space that described first annular slot surrounds 2 parallel
Second rectangular aperture, the two ends of described each second rectangular aperture first rectangular aperture described with 2 respectively
End connect.
Preferably, in above-mentioned double-frequency micro-strip antenna, connect between described 2 the second rectangular apertures and have
3rd rectangular aperture, the 3rd rectangular aperture is vertical with the second rectangular aperture.
Preferably, in above-mentioned double-frequency micro-strip antenna, described 3rd rectangular aperture is connected to described second
The middle part of rectangular aperture.
