Abstract

The invention discloses a dual trapped wave flat ultra wideband antenna which consists of a medium substrate (1), a radiation unit (2) and a signal feed band wire (3), wherein a circular complementation opening resonance ring (CSRR) structure (4) is arranged on the radiation unit; the signal feed band wire is provided with a U-shaped slot (5); the radiation unit and the signal feed band wire are both printed at the upper surface of the medium substrate; the radiation unit is positioned in the middle of the medium substrate; a feeder is led to the radiation unit from the margin of the medium substrate and connected with the same, and a grounding surface is printed at the lower surface of the medium substrate. The dual trapped wave flat ultra wideband antenna is compact in structure and small in size; trapped wave frequency can be regulated by changing the size and position of the U-shaped slot and the circular complementation opening resonance ring (CSRR) structure, and the problem of same frequency interference of an ultra wideband communication system is solved.

Description

Two trap plane ultra-wideband antenna
Technical field
The present invention designs a kind of antenna, is specifically related to a kind of two trap plane ultra-wideband antenna.
Background technology
Since FCC, (Federal Communications Commission) allows 3.1---and since the commercialization of 10.6GHz frequency range, super-broadband tech obtains at academic and commercial field and broadly pays close attention to.Do not need to hole and be easy to integrated coplanar waveguide structure to make rapid progress, and this structure can be made by camera technique, and have good polarization characteristic, therefore this technology has been applied in the design of ultra-wideband antenna and the design of relevant microwave circuit components and parts.
But the frequency band shared by current ultra-wideband communications and WiMAX, WLAN (wireless local area network) have shared part, therefore need the antenna designed to reduce and bring interference to it, 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 the ultra-wideband antenna designed with trap characteristic is one of important method of head it off, solves the problem of the Structure and energy more complicated of current antenna simultaneously.
