Technical field
The invention belongs to antenna technical field, particularly the structure of antenna radiation unit and ground connection form.
Background technology
(Ultra-Wide Band, UWB) wireless communication technology has advantages such as system configuration is simple, message transmission rate is high, ability low in energy consumption, safe, multi-path resolved is strong to ultra broadband.On February 14th, 2002, the approval that super-broadband tech has obtained FCC (FCC) first is used for commercial communication, formally 3.1～10.6GHz frequency band is opened to the UWB as the indoor communications purposes, thereby has been caused the extensive concern of countries in the world.UWB is particularly useful in the high-speed radio access and military communication application in place such as indoor multi-path dense such as grade.
The ultra-wideband antenna technology is one of key technology of super broad band radio communication.Conventional ultra-wideband antenna mainly comprises and adds ridged horn antenna, TEM horn antenna, helical antenna and biconical antenna etc., and they all have very wide working band, but this class antenna belongs to stereochemical structure more, is difficult to and the system integration.Because many ultra broadband terminal equipments mostly are portable mobile unit, thus require ultra-wideband antenna to have planar structure, and volume is little.
Plane single pole sub antenna since have volume little, simple in structure, easily with advantage such as the system integration, favor and be subjected to people.
In addition, in the working range of radio ultra wide band system 3.1～10.6GHz, also exist other narrow-band communication system, as WLAN (WLAN (wireless local area network)) be operated in 2.4GHz (2400～2484MHz), 5.2GHz (5150～5350MHz) and 5.8GHz (5725～5825MHz) locate, and they and radio ultra wide band system can form and interfere with each other.Therefore, need a kind of ultra-wideband antenna of design, with the interference that suppresses to exist between radio ultra wide band system and narrowband systems with stopband characteristic.
Summary of the invention
The object of the present invention is to provide a kind of novel ultra-wideband monopole antenna with dual-attenuation characteristic.
The present invention constitutes radiating element by microstrip-fed regular hexagon, to obtain the ultra broadband characteristic, and on radiating element, carved the double C shape groove of horizontal positioned, make this ultra-wideband antenna have the dual-attenuation characteristic, change length, width, the distance between the position on regular hexagon top, two C shape grooves of C shape groove etc., i.e. the centre frequency of scalable dual-attenuation and bandwidth.This just can eliminate potential interference between ultra-wideband communication system and other narrow band width wireless communication systems.
The present invention includes a medium substrate [1], a side of medium substrate [1] is printed with metal ground plate [2], and the opposite side of medium substrate [1] is printed with radiating element [3] and feed element [5].Wherein:
A. radiating element [3] is a regular hexagon, has carved two C type grooves [4] in the position of portion on the lower side in the center of circle of radiating element [3], and C type groove [4] is not closed ring; B. radiating element [3] directly links to each other with feed element [5]; C. metal ground plate [2] is trapezoidal metal patch.
Length, the width that the present invention can be by changing C type groove [4], the distance between two C shape grooves, two C shape grooves are from orthohexagonal distance, all can change resonance frequency, make the centre frequency and the bandwidth change of two stopbands, the frequency of stopband is moved down or on move.
Metal of the present invention connects the transition line that base plate [2] has adopted straight line, is used for impedance matching, increases bandwidth of operation.
Feed element of the present invention [5] is microstrip-fed;
The relative dielectric constant of dielectric-slab of the present invention [1] (ε r) is 2-8, and its dielectric loss angle tangent (tg δ) is not more than 10
-3
Radiating element of the present invention is except can adopting the regular hexagon shape, and other have the radiating element form of ultra broadband characteristic also can to adopt octagon etc.The size of radiating element can be adjusted according to concrete needs.
The length of each C type groove of regular hexagon radiating element and width change, and can change resonance frequency, and the centre frequency of stopband is changed, the frequency of stopband is moved down or on move.
The present invention not only has good ultra broadband characteristic, and simultaneously antenna also has the dual-attenuation characteristic, can eliminate and the influencing each other of other narrow band width wireless communication systems; The double-stop band frequency of antenna can be by changing C shape groove length, width, distance, two the C shape grooves between two C shape grooves regulate from factors such as orthohexagonal distances, promptly have the stopband adjustability, therefore can satisfy the application of some special occasions; It is little also to have size simultaneously, in light weight, low-loss, simple in structure, satisfy the requirement of planar design, be convenient to active circuit integratedly, be fit to mobile compact apparatus and use, have characteristics such as cost is low, precision is high, good reproducibility, be fit to advantages such as production in enormous quantities, the equipment that particularly has similar regular hexagon shape for profile can well carry out conformal design with it, has extraordinary development prospect.
