Title:
ANTENNA DEVICE USE BOARD AND ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/188467
Kind Code:
A1
Abstract:
Provided are an antenna device use board and an antenna device that allow flexible adjustment of multi-resonated resonance frequencies and further allow reduction in size and thickness. Included are: a board main-body; first to fourth elements (EL1 to EL4) that are pattern-formed on the board main-body by use of respective metal foils; and a ground surface (GND). The first element (EL1) extends such that the base end of the first element is provided with a feeding point (FP) and further the first element has an antenna component (AT). The second element (EL2) extends such that the base end of the second element is connected to the first element. The third element extends such that the base end of the third element is connected to the feeding point. The fourth element extends such that the base end of the fourth element is connected to the third element. The first to fourth elements extend such that the adjacent ones of those elements and the ground surface are spaced from one another so as to allow generation of the stray capacitance between the adjacent elements and the stray capacitance between each element and the ground surface.
