Abstract:
A printing device can be fabricated in a large size, and a method of patterning a thin film using the same are disclosed. The printing device includes a printing roller that rolls on a substrate to form a thin film thereon. A plurality of blankets are adhered to the printing roller and coated with an organic liquid for the thin film.
Abstract:
Disclosed herein is a chip antenna for terrestrial DMB. The chip antenna comprises a dielectric block, a main antenna device formed with conductive patterns in the dielectric block such that a plurality of unit lamination structures of the conductive patterns having a meander line structure in the direction of the Z-axis in an XZ plane are arranged in the direction of the Y axis while adjacent unit lamination structures are connected to each other, forming a lamination structure having the meander line structure in the directions of the Y-axis, and the plurality of lamination structures are arranged in the direction of the X-axis and adjacent lamination structures are connected to each other in the direction of the X-axis to have the meander line structure, and a T-shaped assistant antenna device formed at an upper or lower dielectric layer in the main antenna device.
Abstract:
Disclosed herein is a multi-layered chip antenna using double coupling feeding. The multi-layered chip antenna comprises a first feeding radiation element including a first feeding electrode connected at one side of the first feeding electrode to a feeding line and connected at the other side thereof to a ground surface while being formed on a first plane in a predetermined direction, the first feeding radiation element being connected to the first feeding electrode so that the first feeding radiation element has a spatial meander line structure, a second feeding radiation element connected to a portion of the first feeding electrode on a second plane parallel to the first plane such that the second feeding radiation element has a planar meander line structure, a second feeding electrode connected to a portion of the first feeding electrode on a third plane parallel to the first plane, a first parasitic radiation element electrically coupled to the second feeding electrode, and a second parasitic radiation element electrically coupled to the second feeding electrode and comprising a plurality of parasitic patterns.
