Description
Technical field
The present invention relates to a kind of ultra-wideband antenna of integrated filter, this antenna can be used for accepting and emitting radio wave.On civilian, can be used as on the terminal receiving equipment of super broad band radio communication.
Background technology
Because radio communication equipment and electronic message unit be towards multifunction, miniaturization, ultra broadband and the friendly direction of coordinating with surrounding environment develop, and this makes broadband, miniaturization, high-gain becomes one of hot subject of domestic and international research.In recent years, the microstrip antenna technical development is maked rapid progress, and this structure can make by camera technique, and polarization characteristic is preferably arranged, so in the design of the design that has been applied in ultra-wideband antenna of this technology and relevant microwave circuit components and parts.Yet frequency band that present ultra-wideband communications is shared and WLAN (wireless local area network) have shared part, therefore need the antenna of design to reduce, even can not bring interference, so the ultra-wideband antenna of design integrated filter structure becomes the focus of present research to wireless local area.If there is not suitable design to suppress harmonic resonance and parasitic emission, such antenna will produce electromagnetic interference near equipment, jeopardize the operate as normal of system itself and neighbor systems, particularly the wireless local area network (WLAN) system to present use causes serious disturbance.Therefore add filter and be the method for the most normal use, the interpolation suitable filters solves between antenna element and radio frequency component system finishes after.Common this method can cause antenna and microwave circuit not to match, even lowers the overall efficiency of system, and the miniaturization of very difficult realization equipment, so the ultra-wideband antenna of integrated filter structure is one of important method of head it off.There are some shortcomings in the existing simultaneously antenna that addresses this problem: the structure and the technology more complicated of the antenna that (1) is at present designed, so the simple antenna of project organization becomes the focus of present stage research.(2) present most of ultra-wideband antenna needs boring usually when the system integration, modes such as use reactance component are connected with radio-frequency front-end, therefore increase the complexity of system, have reduced the usefulness of system, can not satisfy the demand of miniaturization.
Traditional printing ultra-wideband antenna mainly is cone antenna and printing discone antenna, in order to reduce volume, Chinese patent " a ultra broadband ladder floor printing monopole antenna, application numbers 2005100242288.7 " has been set forth a kind of ultra-wideband antenna based on notch cuttype ground plate and oval radiating element.But still can not overcome present electromagnetic interference problem.Document " Harmonic Control For An Integrated Microstrip Antenna With Loaded Transmission Line; Shun-Yun Lin; Kuang-Chih Huang, and Jin-Sen Chen.Microwave And Optical Technology Letters, Vol.44; No.4; February, 2005 " proposes a kind of periodic structure that utilizes and suppresses harmonic wave, but volume is bigger, and complex structure.In order to overcome above-mentioned shortcoming, document " Design of a 5.8-GHz Rectenna Incorporating a New Patch Antenna; Ching-Hong K.Chin, Quan Xue, Chi Hou Chan; IEEE Antennas And Wireless Propagation Letters; Vol.4,2005 " has been set forth the method for etching filter on the coplanar wave guide feedback line, play the characteristic of trap, but volume is still bigger.Document " IETMicrow.Antennas Propag.; 2009; Vol.3, Iss.8, pp.1224 1231. for A miniaturized monopole antenna for ultra-wide band applications with band-notch Filter; B.Ahmadi, R.Faraji-Dana " has been set forth the ultra-wideband antenna that has trap characteristic of etching U-lag and V-shaped groove, but volume is bigger, and adopt the gradual change feed structure, cause complex structure, design and debug difficulties.
Summary of the invention
The object of the present invention is to provide a kind of bandwidth wide, the radiation efficiency height can reduce the ultra-wideband antenna to the integrated filter of the electromagnetic interference between WLAN (wireless local area network) and the ultra-wideband communications.
The object of the present invention is achieved like this: it comprises medium substrate, be arranged on the microstrip-fed structure of radiating element of medium substrate one side, the medium substrate another side is provided with partly structure, and split ring resonator is arranged on the radiating element, and microstrip line directly is connected with radiating element.
The present invention can also comprise:
Described radiating element is a rectangular patch corner cut structure, and described split ring resonator is the annular split ring resonator.
Described radiating element is the rectangular patch structure, and described split ring resonator is the rectangular aperture resonant ring.
The position of described partly structural printing below the microstrip-fed structure of the another side of medium substrate, and partial earthing adopts rectangle corner cut structure.
It is wide to the invention provides a kind of bandwidth, the radiation efficiency height, and the ultra-wideband antenna of integrated filter structure, this antenna can use at electronic reconnaissance, on the equipment such as electronic countermeasures, reduce the electromagnetic interference between WLAN (wireless local area network) and the ultra-wideband communications.
The invention belongs to the planographic monopole antenna, this antenna is printed on the medium substrate, and its radiating element adopts rectangular patch corner cut structure, helps increasing the bandwidth of antenna.The ultra-wideband antenna of designed integrated filter structure adopts simple microstrip-fed structure, and so direct employing edge feed helps reducing the complexity of antenna, is convenient to debugging and produces.Split ring resonator structure of etching plays the effect of filter on radiating element, avoids the electromagnetic interference between ultra-wideband communication system and the already used narrowband systems.This antenna has good impedance bandwidth and filter characteristic, and is simple in structure, therefore increased its scope of application greatly.The present invention adopts printed antenna structure and microstrip-fed structure, greatly reduces antenna volume, and more integrated than being easier to the radio-frequency front-end microwave integrated circuit.
The present invention compared with prior art has significant advantage: the present invention can realize the impedance bandwidth of ultra broadband; The designed antenna of the present invention is printed on two sides on the medium substrate, by rectangular patch radiating element, microstrip-fed structure, structure and be etched in the ultra-wideband antenna that split ring resonator on the radiating element constitutes integrated filter structure partly; This antenna directly adopts little band edge feedback technology, helps reducing the complexity of antenna, is convenient to actual production and debugging; The antenna integrated filter structure that the present invention is designed effectively reduces the volume of system; The integrated filter of etching on this antenna effectively reduces ultra-wideband communications to the interference between the wireless lan (wlan); In system design, reduce the usage quantity of filter simultaneously like this, help improving the usefulness of system, thereby improve the efficient of system; This antenna structure is simple, compactness, and volume is little, and is easy to process, and cost is low.
