Abstract: Provided are an antenna device, a method of manufacturing the same, and an electronic apparatus having the antenna device. The antenna device includes: an insulating substrate; a first antenna pattern formed on one surface of the insulating substrate; and a second antenna pattern formed on the other surface of the insulating substrate and connected to the first antenna pattern.

Abstract: Provided is a large-capacity metal catalyst support and a catalytic converter using the same, in which a number of unit catalyst support blocks are changed in a form of being effectively assembled so as to be applied to a catalytic converter that is required for processing a large amount of exhaust gas such as large vessels or plants employing a number of large-scale internal combustion engines, or large food processing devices, to thus easily assemble the unit catalyst support blocks into a large-scale assembled structure. The catalyst support includes: a number of unit catalyst support blocks in which cell formation bodies formed of a number of hollow cells that are aligned in a longitudinal direction are accommodated and stacked in a polygonal supporter wherein a catalyst is coated on the surfaces of the hollow cells; and a number of assembly members each for fixing a pair of adjacent supports that mutually contact between the stacked unit catalyst support blocks.
