Automotive electronics label is typically mounted on shield glass, under normal circumstances, this label can normally be arrived by pavement detection equipment Inspection, but when adopting aluminum paper tinsel, when the electronic tag back side is covered by the materials such as Copper Foil, pavement detection equipment just cannot normally detect, this is because electronic tag is when near metal surface, its performance meeting degradation, lawless person may adopt back to press close to the means such as metal and make the hydraulic performance decline of label, cannot be read by road surface equipment, the information causing vehicle cannot be recorded, thus realizing fee evasion or escaping monitoring.
The existing electronic tag being pasted onto windshield is dipole antenna, when not having the objects such as metal when sign perimeter, functional; But when adopting metal or palm to be close to label back, road surface equipment cannot read the information of label substantially.
Someone adopts the nearly thing interference problems of formal solution award of bid label such as microstrip antenna, and nearly thing disturbs and disturbs without nearly thing, and the performance of label is all similar. But poor performance is very many when this kind disturbs without nearly thing than existing electronic tag. Namely solve the special circumstances of application, but make ordinary circumstance be deteriorated. And the microstrip antenna gain of standard card size is relatively low, it is impossible to meet the requirement used; Microstrip antenna processing technology makes it cannot solve the application such as the tamper of electronic tag for vehicles, and this all makes this kind of mode substantially be abandoned.
Problem in sum is that existing label antenna cannot in two kinds of different application scenes, and namely there are metal and back in back without in metal situation, and performance is all good.When being without metal to the demand that electronic tag for vehicles is basic in industry, tag performance is good, meets all of performance requirement; When having metal, it is possible to by road surface equipment Inspection to.
