Description
Technical field
The present invention relates to a kind of new Ultrawide-band trap antenna based on W shape cuttings, in the radiation of antenna
A W-shaped groove is carved on the 3 of antenna and realizes double trap functions, antenna radiation unit uses pentagon paster structure.
The antenna realizes the ultra wideband transmissions characteristic (standing-wave ratio is less than 2) from 3.1GHz to 10.6GHz, and divides
Trap is not carried out in 5.6~6.4GHz, 8.8~9.4GHz, two narrowband slices, is effectively reduced and two frequency range
Between interference.
Ultra-wideband Communication Technology is widely used in the fields such as radar, positioning, electronic countermeasure and secret communication,
It is considered as sophisticated military technology and close protection by various countries for a long time, just gradually tends to civilian until in recent years.It is super
The advantage of broadband communications technologies system can be summed up as follows：1. highly concealed type.2. stronger multipath identification capability and compared with
The rate of information throughput high.3. power system capacity is big.4. penetration capacity is strong, it is easy to accomplish positioning and the one for communicating
Change.5. it is low in energy consumption.
Ultra-wideband antenna is one of key components of super broad band radio communication system, and its design needs to consider
Two aspect contents：1. realize the ultra wideband transmissions characteristic from 3.1GHz to 10.6GHz (standing-wave ratio is less than 2)；
2. the mutual interference problem with other narrow-band communication systems is considered, possesses certain while antenna carries out broadband communications
The trap function of a little narrowband slices.2 points of considerations based on more than, occur in that traditional with trap function ultra wide band
The method for designing of antenna, i.e., by Analysis of Equivalent Circuit, some are increased on antenna radiation unit has specific work(
The slotted eye (such as L-type groove, U-type groove) of energy, to reach required trap purpose.
Background technology
The original form of super-broadband tech [1-3] is impulse wireless communication, originates from the forties in 20th century,
Low detecing uses in the communication equipments such as side rate.In recent years, with microelectronic component technology and technique raising,
UWB technology starts to be applied to civil area.Ultra-wideband communications are a kind of without carrier wave, and by very
One kind that the pulse of steep rising and falling time is modulated (generally, pulse width is between 0.20-1.5ns) is led to
Letter, also referred to as impulse radio (Impulse Radio) time domains (Time Domain) or carrierfree (Carrier Free)
Communication.It has the bandwidth of GHz magnitudes, and because its emitted energy is fairly small, it is thus possible to it is being not take up now
A kind of brand-new voice and data communication mode are brought in the case of crowded to capacity frequency resource.
After the frequency band of 3.1GHz to 10.6GHz is used by Federal Government developer, ultra wide band day
Line just has been a great concern.Because the data processing speed being exceedingly fast and to eliminate part multipath effect do
Disturb, ultra-wideband antenna is considered as one of outlet of following flirtatious communication system.Because the inside of ultra-wideband antenna sets
Meter with conflict composition can not perfectly be matched including impedance, and radiate stability ultra-wideband antenna chi
It is very little etc., so ultra-wideband antenna also receives certain limitation during development.Coplanar wave guide feedback day
Line has lot of advantages such as bandwidth very wide, and preparation price is low to be easy to and frequency of radio station compatibility
Before in order to improve the bandwidth of paster antenna by many schemes, such as use one relatively
Thick dielectric-slab, using the shunt resonators of low conducts constant, stacks multiple parasitic pasters on main paster,
Or placing multiple pasters, U-shaped cutting, L-type probe, lossy medium near the place of main paster
Etc..The radiation patch of printed antenna has a variety of form triangles, and rectangle is oval, circular square,
It is also a lot.

Specific embodiment
Because the ultra-wideband antenna works in microwave frequency band, will divide by microwave transmission line theory here
Analyse its radiation theory.Assuming that the radius of paster antenna triangle radiating element is half wavelength lambda/2, medium substrate
Thickness is L3.So, triangle radiating element, medium substrate and earth plate can be regarded as a length of λ/2
Low ESR microstrip transmission line, and form open circuit in radiating element edge.Again because dielectric substrate thickness is far small
In wavelength X, thus electric field is substantially unchanged along the component in paster plane normal direction.Only considering principal-mode excitation
In the case of, electromagenetic wave radiation may be considered what is caused by the edge at radiating element open circuit position substantially.Can be with
The electric field of open end is decomposed into the horizontal component along paster plane and the vertical component parallel to plane normal, its
Middle vertical component is cancelled out each other because of opposite in phase, therefore the horizontal component of electric field makes radiating element open end equivalent
It is the gap of cophase detector on infinity plane.So, radiating element is just equivalent into gap to external radiation
Radiation.
