Title:
MULTI-BAND ANTENNA AND RADIO COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/159369
Kind Code:
A1
Abstract:
This multi-band antenna is provided with: a conductor reflecting plate having a plate surface; a first antenna element which extends a distance corresponding to a first wavelength along the plate surface of the conductor reflecting plate; and a second antenna element which extends a distance corresponding to a second wavelength, shorter than the first wavelength, along the plate surface of the conductor reflecting plate. The distance between the first antenna element and the plate surface in a perpendicular direction, which is a direction perpendicular to the plate surface, is equal to the distance between the second antenna element and the plate surface in the perpendicular direction.
