ANTENNA DEVICE AND RADIO COMMUNICATION APPARATUS
Document Type and Number:
Japanese Patent JP2015154328
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna device which can be relatively small-sized in comparison with a wavelength of a subjected frequency.SOLUTION: A balun 400 is provided between a feeding point 300 of a circuit board 310 in which a transceiver circuit is provided, and first and second antenna elements 302-1 and 302-2. The first antenna element 302-1 and the second antenna element 302-2 operate as dipole antennas. The circuit board 310 between the first antenna element 302-1 and the second antenna element 302-2 is floating in a high frequency manner by means of the balun 400.
