Abstract:
A dual-interface smart card having a booster antenna with coupler coil in its card body, and a metallized face plate having a window opening for the antenna module. Performance may be improved by one or more of making the window opening substantially larger than the antenna module, providing perforations through the face plate, disposing ferrite material between the face plate and the booster antenna. Additionally, by one or more of modifying contact pads on the antenna module, disposing a compensating loop under the booster antenna, offsetting the antenna module with respect to the coupler coil, arranging the booster antenna as a quasi-dipole, providing the module antenna with capacitive stubs, and disposing a ferrite element in the antenna module between the module antenna and the contact pads.

A manufacturing method of electronic packaged device includes the following. A plurality of electronic components is disposed on a substrate carrier. An encapsulating member is disposed on the substrate carrier and covers the electronic components. The substrate carrier is separated from the encapsulating member. A plurality of first trenches is arranged on a first surface of the encapsulating member. Conductive material is disposed onto the first surface and into the first trenches to form a conductive layer. The conductive layer is patterned on the first surface to form a circuit layer. The circuit layer includes at least one grounding pad. A plurality of second trenches is arranged on a second surface of the encapsulating member. At least one shielding structure is formed in the first trenches and the second trenches. An electromagnetic shielding layer is connected to the grounding pad.
Abstract:
A method of making an imprinted optical micro-channel structure for transmitting light to an optical receiver or receiving light from an optical transmitter includes forming a curable optical layer over a substrate and imprinting one or more optical micro-channels in the optical layer with a first stamp. The curable optical layer is cured to form a cured optical layer having the optical micro-channels imprinted in the cured optical layer. A curable light-transparent material is located in the optical micro-channels and cured to form light-pipes of cured light-transparent material in the optical micro-channels. The optical transmitter located in alignment with a light-pipe for transmitting light through the light-pipe or the optical receiver is located in alignment with a light-pipe for receiving light from the light-pipe.
