An antenna apparatus for a portable terminal having a main board is provided. The antenna apparatus includes a main antenna that electrically connects to a feed line of the main board. A metal frame is constructed as part of a case frame forming an exterior of the portable terminal The metal frame is divided into first and second parts that are separated. The first part electrically connects to the main antenna or to the main board feed line, and is designed to radiate. The second part electrically connects to a ground surface of the main board. The metal frame enhances overall antenna performance rather than causing degradation through interference.
Abstract:
Highly-ordered block copolymer films are prepared by a method that includes forming a polymeric replica of a topographically patterned crystalline surface, forming a block copolymer film on the topographically patterned surface of the polymeric replica, and annealing the block copolymer film. The resulting structures can be used in a variety of different applications, including the fabrication of high density data storage media. The ability to use flexible polymers to form the polymeric replica facilitates industrial-scale processes utilizing the highly-ordered block copolymer films.

Abstract:
A Multiple-Input Multiple-Output (MIMO) antenna system with multiple antennas is provided. The MIMO antenna system includes a number of conductive elements, and a number of band stop devices. The conductive elements are spaced apart from each other and operate in corresponding resonant frequency bands respectively when they receive electric power. When the conductive elements are operated, the band stop devices block interference between the conductive elements in the resonant frequency bands, and isolate the conductive elements from each other. The band stop devices are located between adjacently separate conductive elements and connect the conductive elements to each other. The MIMO antenna system can stop interference between the conductive elements via the band stop devices, thereby increasing the operational efficiency of the conductive elements.

A method of forming a polycrystalline silicon layer and an atomic layer deposition apparatus used for the same. The method includes forming an amorphous silicon layer on a substrate, exposing the substrate having the amorphous silicon layer to a hydrophilic or hydrophobic gas atmosphere, placing a mask having at least one open and at least one closed portion over the amorphous silicon layer, irradiating UV light toward the amorphous silicon layer and the mask using a UV lamp, depositing a crystallization-inducing metal on the amorphous silicon layer, and annealing the substrate to crystallize the amorphous silicon layer into a polycrystalline silicon layer. This method and apparatus provide for controlling the seed position and grain size in the formation of a polycrystalline silicon layer.
