Description
Technical field
The present invention relates to a kind of antenna, a kind of ultra-wide of new hollow defect ground structure of specific design
Band antenna.
Background technology
Since FCC (FederalCommunicationsCommission) allows 3.1 --- 10.6GHz
Since frequency range commercialization, super-broadband tech has obtained broadly paying close attention in academic and commercial field, while also being carried to ultra-wideband antenna
Requirement higher is gone out, has been allowed to the design more challenge than traditional antenna, be mainly manifested in:Antenna is except needing with ultra-wide
Working band (generally 3.1GHz -10.6GHz), can also keep the compact of size, weight it is frivolous, and be easy to
It is integrated with plane large-scale circuit.
However, the frequency band and WLAN shared by current ultra-wideband communications have shared part, it is therefore desirable to design
Antenna can be reduced and bring interference to WLAN, and ultra-wideband antenna of the design with double trap characteristics turns into the heat of research at present
Point.If suppressing harmonic resonance and parasitic emission without appropriate design, antenna will produce electromagnetic interference to neighbouring equipment,
Jeopardize system in itself with the normal work of neighbouring system, particularly the LAN system for using at present is interfered.Addition filter
Ripple device is the method for most-often used solution problems, but often causes antenna and microwave circuit to mismatch, or even reduces system
The overall efficiency of system, therefore it is to solve this to ask that design has the ultra-wideband antenna of a kind of new defect ground structure of double trap characteristics
One of important method of topic, while solving the problems, such as that the structure and technics comparing of current antenna are complicated.
The content of the invention
It is an object of the invention to provide a kind of simple structure, compact, broader bandwidth with trap characteristic
Ultra-wideband antenna, the antenna can be used on the military equipments and civil equipment such as electronics investigation, electronic countermeasure, reduced to broadband
Intercommunication microwave accesses WiMAX (3.3~3.6GHz), WLAN WLAN (5.15~5.825GHz).
The technical solution adopted in the present invention is:
A kind of ultra-wideband antenna of new hollow defect ground structure, it is characterized in that:Including medium substrate, radiating element is micro-
Band transmission line, hollow defect ground structure, ground plane, described radiation element, microstrip transmission line be printed on medium substrate upper surface,
Hollow defect ground structure is etched on earth plate, and described ground plane is printed on the back side of medium substrate.
The ultra-wideband antenna of described a kind of new hollow defect ground structure, it is characterized in that:Described microstrip line both sides difference
There are two Metal cavities of symmetrical structure.

Metal cavity size is unequal.
The ultra-wideband antenna of described a kind of new hollow defect ground structure, it is characterized in that:Described Metal cavity etching
On earth plate.
Concrete structure:
(1) there is the Metal cavity of symmetrical structure present invention microstrip line both sides on medium substrate, make antenna in frequency
Rate scope 3.1GHz -10.6GHz has double trap characteristics, and bandwidth is also wide.
(2) inventive antenna single layer printed circuit plate technique is to be capable of achieving, simple and compact for structure, compact, plus
Work is convenient, low cost.
