Title:
CIRCULAR POLARIZED WAVE PATCH ANTENNA AND RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3445431
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To realize a circular polarized wave which is omnidirective within a horizontal surface.
SOLUTION: In this system, each of a first patch antenna 12 and a second patch antenna 13 are arranged on each surface side of an earth conductive plate 11. At this time, the first patch antenna 12 and the second patch antenna 13 are composed so that the first image current 14 for the first patch antenna 12 and the second image current 15 for the second patch antenna 13 which flow in the earth conductive plate 11 may cancel with each other.
