Abstract

According to one embodiment, there is provided an antenna device including a base substrate having a power-feeding pattern, and a stackable block stacked on the base substrate and fixed to the surface of the base substrate, the stackable block having an element pattern with one end connected to the power-feeding pattern and the other end extendible in a direction of stacking another stackable block on the stackable block.

Description

technical field [0001] One embodiment of the present invention relates to an antenna arrangement suitable for a transportable small electronic device equipped with a radio unit. Background technique [0002] Internal antennas using printed circuit boards are often used in small transportable electronic devices equipped with radio units. An internal antenna using a printed circuit board is constructed by forming, on the printed circuit board, an element pattern having a printed wiring board structure, which functions as an antenna radiator. Similar to circuit wiring patterns in printed wiring boards, component patterns are made of conductive foil. In a conventional antenna device using such a printed circuit board, element patterns are formed on a single board or a multilayer board. Such antenna devices are disclosed, for example, in Japanese Patent Application KOKAI Publication Nos. 2002-100915, 2005-005987 and 2004-186730. [0003] In the above conventional antenna devic...
