Description
Technical field
The utility model relates to a kind of antenna, a kind of ultra-wideband antenna based on circular arc rectangular configuration groove of specific design, and on this basis, realize the trap function in WLAN signal frequency range.
Background technology
Along with the develop rapidly of mobile communication, the requirement of communication system to the beamwidth of antenna is more and more higher.Since FCC (Federal Communications Commission) is since on February 14th, 2002 allows the commercialization of 3.1-10.6GHz frequency range, super-broadband tech obtains at academic and commercial field and broadly pays close attention to, higher requirement be it is also proposed to ultra-wideband antenna simultaneously, make it to have more challenge than the design of traditional antenna, be mainly manifested in: antenna is except needing to have the working band (being generally 3.1GHz-10.6GHz) of ultra-wide, also want to keep the compact of size, weight frivolous, and be easy to integrated with plane large-scale circuit.
But the frequency band shared by current ultra-wideband communications and WLAN (wireless local area network) have shared part, therefore need the antenna designed to reduce and bring interference to WLAN (wireless local area network), the ultra-wideband antenna that design has trap characteristic becomes the focus studied at present.If do not have suitable design to come harmonic inhabitation resonance and parasitic emission, antenna produces electromagnetic interference by neighbouring equipment, jeopardizes the normal work of system itself and contiguous system, particularly causes interference to the LAN system used at present.Add the method that filter is the solution problems the most often used, but often cause antenna and microwave circuit not to mate, even reduce the overall efficiency of system, therefore design has the ultra-wideband antenna based on circular arc rectangular configuration groove of trap characteristic is one of common method of head it off, solves the problem of the Structure and energy more complicated of current antenna simultaneously.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, compact, the circular arc ultra-wideband antenna with trap characteristic of broader bandwidth, bandwidth range is at 2.03 ~ 15.1GHz, impedance bandwidth reaches 174%, complete covering ultra wideband frequency range, and by rectangular configuration groove on this basis, realize trap function in WLAN frequency range, reduce the interference of WLAN signal.This antenna can be used in the military equipments such as electronics investigation, electronic countermeasures and civil equipment.
Technical scheme described in the utility model is:
Based on the ultra-wideband antenna of circular arc rectangular configuration groove, it is characterized in that: comprise medium substrate, circular arc radiation patch unit, rectangular configuration groove, microstrip transmission line, ground plane.Described circular arc radiating element, microstrip transmission line, rectangular configuration groove are all printed on medium substrate upper surface, and described ground plane is printed on the back side of medium substrate.
The described ultra-wideband antenna based on circular arc rectangular configuration groove, is characterized in that: radiating element is circular arc grading structure.
The described ultra-wideband antenna based on circular arc rectangular configuration groove, is characterized in that: radiating element paster is opened rectangular configuration groove.
Concrete structure:
(1) radiation patch unit of the present utility model adopts gradation type arc-shaped structure Bandwidth.
(2) described in the utility modelly on radiating element, carve rectangular configuration groove, by regulating the position of the concrete adjusted size trap frequency of rectangular configuration groove, thus realize ultra-wideband communications and disturb compatible communication for coordination between communication system mutually.
(3) single layer printed circuit plate technique can realize, simple and compact for structure, and compact is easy to process, and cost is low, is convenient to batch production.

Embodiment
Antenna example:
As shown in Figure 1, there is the ultra-wideband antenna based on circular arc rectangular configuration groove of trap characteristic, its composition comprises: medium substrate (1), circular arc radiation patch unit (2), rectangular configuration groove (3), microstrip transmission line (4), ground plane (5).Described circular arc radiating element, microstrip transmission line, rectangular configuration groove are all printed on medium substrate upper surface, and described ground plane is printed on the back side of medium substrate.
Described medium substrate is polytetrafluoroethylene material, thickness 1.6mm, and relative dielectric constant is 2.55.
Described radiating element has gradation type arc-shaped structure, realizes the ultra broadband characteristic of antenna.
Described microstrip transmission line characteristic impedance 50 Ω, live width 3.5mm, realizes good impedance matching.
Ultra-wideband antenna based on circular arc rectangular configuration groove has good trap characteristic.The bandwidth range of this antenna is 2.03 ~ 15.1GHz, reaches the requirement of ultra-wideband antenna bandwidth, and complete covering ultra wideband antenna frequencies scope, antenna standing wave ratio is less than or equal to the impedance bandwidth 2.03 ~ 15.1GHz of 2, meets the demand of ultra-wideband communications.According to the rectangular groove structure loaded, trap characteristic is realized in impedance bandwidth range, within the scope of 5.11 ~ 5.98GHz, value is greater than 2, there is larger reflected wave, frequency range just in time covers WLAN signal frequency band, effectively can suppress the interference of WLAN frequency band signals, well eliminate or reduce ultra-wideband antenna to the interference of electromagnetism, realizing good communication requirement.
