Title:
ANTENNA AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/148274
Kind Code:
A1
Abstract:
Disclosed is a small antenna for wireless communication, said small antenna being provided with: a light reflector substrate; a dielectric substrate disposed on the light reflector substrate; a radiation element, which is formed on the main flat surface of the dielectric substrate, and emits electromagnetic waves; a power supply unit, which is provided on the main flat surface of the dielectric substrate, and supplies power to the radiation element; and a plurality of split-ring resonant units that are formed in a region of the main flat surface of the dielectric substrate, said region being between the radiation element and the light reflector substrate. The light reflector substrate reflects the electromagnetic waves toward the light reflector substrate, said electromagnetic waves having been emitted from the radiation element. Each of the split-ring resonant units has: a split section having a first end section and a second end section, which are facing each other by being separated from each other; and a ring section that connects the first end section and the second end section to each other.
