Description
Technical field
The present invention relates to be used for the micro-strip paster antenna field of the support multi-frequency work of radio communication, particularly a kind of fabric microstrip antenna of the be worn on human body of forming by fabric.
Background technology
Antenna is a kind of with plain conductor, metal covering or other dielectric materials formation definite shape; Be erected at the device of certain space; It will convert the electromagnetism wave energy to space radiation from the radio-frequency electrical energy that transmitter is fed into, perhaps be converted into the electromagnetism wave energy of spatial transmission radio-frequency electrical energy and will be transported to receiver.
Microstrip antenna is a kind of of antenna.It is on a thin-medium substrate (substrate layer), and one side is enclosed thin metal layer as ground plate (ground plane), and another side is processed the metal patch (antenna patch) of definite shape.
In recent years, the development of portable intelligent system makes the wearable antenna of light softness become a popular topic.Since 2009, the fabric antenna blank progressively produces at European scientific research field.But the defective of the design of frequency bandwidth and polarization (directivity) makes its application receive certain restriction.The wearable fabric microstrip antenna of The Study on Resources is all dropped into the well-known university of a few institute that communicates by letter in Europe at present.
The present invention is the basis with the design principle of microstrip antenna, adopts textile material, and dispense with outer connecting power has reached soft, in light weight, can wear the purpose on clothes.And can change different media as required, support multiple-frequency operation, support circular polarization, dual polarization and multipolarization design simultaneously.To the microstrip antenna field is significant.
Summary of the invention
The invention provides a kind of fabric microstrip antenna, an object of the present invention is to solve traditional antenna and worn difficult problem, another object of the present invention is through changing the medium of different materials, can reaching the different working frequency range.
The technical scheme that adopts is:
A kind of fabric microstrip antenna comprises conductive layer, non-conductive layer, ground plane and Sma connector.This Sma connector is a known product.
Its technical essential is:
Conductive layer is conductive foil or conductive metallization fibrage.Conductive layer comprises microstrip feed line and conductor patch, and microstrip feed line and conductor patch are an overall structure.
Non-conductive layer is a tissue layer, and the upper surface of non-conductive layer is fixed with conductive layer, and the lower surface of non-conductive layer is fixed with ground plane.Ground plane is conductive foil or conductive metallization fibrage.
The splicing ear and the microstrip feed line of Sma connector are fixedly connected, the connecting plate of Sma connector and ground plane
Be fixedly connected.
Described conductive foil thickness is 0.1 to 1 millimeter.
This product adopts textile material can reach the operating frequency of 2-4GHz.Can reach the work of very superior ISM band as required.
To the medium of conductive layer, non-conductive layer and ground plane replacing different materials, can reach wideer operating frequency range among the present invention.
The present invention can extensively combine with various textiles, is worn on human body.For example:
1, fire-fighting protective garment:
Be worn on the fabric microstrip antenna on the firefighter uniform; Cover with fireprotection layer by watertight composition; Antenna is worn on big arm, and links to each other with signal projector on the fire-entry suit, according to the measured value of different sensor; Can fire scene temperature humidity and fireman's palmic rate be breathed near the receiving terminal (fire fighting truck) sending back.
2, spe-cial-purpose uniform such as hospital home for destitute
This fabric microstrip antenna can with patient's position, respiratory rate, palmic rate and pressure value instant send back monitoring station, help nurse and doctor that patient is carried out monitoring in real time in 24 hours.
3, soldier's fighting uniform
Frequency requirement according to satellite communication.The soldier do not carry any heavy equipment just can with satellite communication.
Its operation principle is:
When being used as transmitting antenna:
Input signal (electric energy) gets into antenna by the Sma connector, and the microstrip feed line of flowing through arrives at conductor patch, is converted into electromagnetic wave to electric energy, is transmitted in the air.
When being used as reception antenna:
Electromagnetic wave is received by conductor patch, changes into information (electric energy), through microstrip feed line, is delivered to the Sma connector to the information that receives.
Its advantage is:
Dispense with outer connecting power of the present invention, light softness does not have any discomfort sense when wearing.
Can support the communicating requirement of different frequency, make the transmission of signal multipolarization and circular polarization, make laser propagation effect more superior.
