Title:
RADIO COMMUNICATION APPARATUS AND PRINTER
Document Type and Number:
Japanese Patent JP2005332318
Kind Code:
A
Abstract:
To obtain a radio communication apparatus without need of exclusively designing an antenna.
In the radio communication apparatus 7 which emits electromagnetic waves from the antenna 7a and performs radio communication to an RF tag, a dielectric 8 is provided at a position where the electromagnetic waves emitted from the antenna 7a pass. Thus, it becomes unnecessary to exclusively design the antenna 7a since frequency characteristics of the antenna 7a vary to a direction that frequency is lower by an action of the dielectric 8.
