Title:
ANTENNA, ADJUSTING METHOD OF THE SAME AND ELECTRONIC APPARATUS EQUIPPED WITH ANTENNA
Document Type and Number:
Japanese Patent JP2012134948
Kind Code:
A
Abstract:
To provide an apparatus and a method, which can improve a reflection characteristic when an antenna is loaded and can use the same antenna to different models.
The radio communication antenna is incorporated in an electronic apparatus where an antenna element and a GND part are arranged on a dielectric substrate. An opening conductor which is high frequency-connected to the GND part is installed at an end of the dielectric substrate in a diagonal direction from a feeding point of the antenna element. In the GND part, length in a vertical direction to a travelling direction of a high frequency signal is less than 1/4 of a wavelength of an operation frequency of the antenna element.
