Embodiment 3:
Referring to Figure 11, the present invention provides one kind on the basis of the above embodiments and is applied to power supply, power transmission network assets
Outdoor plastic packaging electronic tag, the plastic packaging electronic tag are ultra-high-frequency passive electronic mark product, can be used for asset identification, chase after
Track, positioning and all kinds of management use.The plastic packaging electronic tag is made of antenna, plastic stent/medium, package casing.Its
Middle antenna is attached at plastic stent upper layer, side and bottom in an orbiting manner (detail is referring to embodiment 1).Antenna exists
Radiation front is formd on plastic stent after, radiates bottom surface and side connection, and form an opening on medium
Cavity.Plastic stent upper and lower level side fluting, enhancing are merged with shell.Plastic stent upper layer corresponds under antenna chip position
Heavy, electronic tag outer casing thickness increases, and improves weather resistance (detail is referring to embodiment 2).Entire antenna, bracket and bottom
Hardened structure is completely sealed in sheathing material, reaching airtight grade, protects internal electronic component, product is existed
It is used for a long time 10 years or more under outdoor harsh environment.
Product shown in Figure 11 is whole by antenna, plastic stent/medium, package casing composition.Plastic stent upper and lower level side
Fluting, avoids shrinking and quadric injection mould enhances and merges with shell.Plastic stent upper layer respective antenna chip position, at sinking
Reason, and gentle slope is handled when sinking.The processing of sinking gentle slope, is pasted convenient for antenna in the region.Sink at plastic stent chip,
Wall thickness above chip can be increased, improve electronic tag weatherability.Core surface shines line processing.Antenna is using adhesive around viscous
It is attached to the upper surface of plastic stent, side and bottom surface.Antenna loop is after being fitted on plastic stent, the structure on plastic stent
At an open-ended cavity.Antenna loop forms aerial radiation front in the upper surface of bracket after fitting, is formed and is radiated in bottom surface
Bottom surface, and front is connected with underrun side attachment areas, mutual conduction.Length after entire antenna expansion is about a quarter
Wavelength.There are three air discharge ducts on Antenna Design, one of them is located at folded bottom surface, and two are located at head-on radiation area.It
