Abstract
The invention discloses a dual-frequency microstrip antenna, which comprises a dielectric layer, a radiation patch and a microstrip feeder formed on one surface of the dielectric layer, and a grounding part formed on the other surface of the dielectric layer, wherein the radiation patch comprises a first radiation section extending along a first direction, a second radiation section and a third radiation section extending to a second direction from two ends of the first radiation section respectively, and a fourth radiation section extending along the first direction from the tail end of the third radiation section; the first direction is vertical to the second direction; a notch is formed between the second radiation section and the fourth radiation section; and the microstrip feeder is vertically connected with the first radiation section. The dual-frequency microstrip antenna has the advantages that the dual-frequency performance can be realized, and the size is small; and through the triangular gradually-change patch arranged at one side, the antenna can smoothly transmit from one resonant frequency to the other resonant frequency.
Description
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.
Summary of the invention
It is an object of the invention to provide a kind of double-frequency micro-strip antenna, to overcome deficiency of the prior art.
For achieving the above object, the present invention provides following technical scheme:
The embodiment of the present application discloses a kind of double-frequency micro-strip antenna, including dielectric layer, is formed at described medium
Laminated radiation patch and microstrip feed line and be formed at the grounding parts of described dielectric layer another side, institute
State the first radiant section that radiation patch includes extending in a first direction, from described first radiant section two ends respectively
The second radiant section extended to second direction and the 3rd radiant section and the end from described 3rd radiant section
The 4th radiant section extended in a first direction, described first direction is vertical with described second direction, and described
Forming a breach between two radiant sections and the 4th radiant section, described microstrip feed line is vertically connected at described first
Radiant section.
Preferably, in above-mentioned double-frequency micro-strip antenna, the side of described microstrip feed line and the first radiant section
Between be formed with the gradual change paster of triangle.
Preferably, in above-mentioned double-frequency micro-strip antenna, described grounding parts offers gap in a second direction,
Described microstrip feed line is positioned at the top in described gap.
Preferably, in above-mentioned double-frequency micro-strip antenna, the width in described gap is more than described microstrip feed line
Width.
Compared with prior art, it is an advantage of the current invention that:
(1), present configuration can realize double frequency performance, size is little simultaneously；
(2) the gradual change paster of the triangle, by side arranged, so that antenna is from a resonance frequency
Rate is the most gently transitioned in another resonant frequency.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality
