Title:
ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2017017542
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna device capable of radiating circular polarization of good axial ratio up to a high frequency band, while obtaining the radiation directivity having symmetry.SOLUTION: A spiral line 2 having a spiral pattern shape symmetric at a midpoint 2a, a spiral line 3 having the same pattern shape as the spiral line 2, and divided at a midpoint 3a are formed at the opposite positions on the front and back of a dielectric substrate 1. A high frequency power supply 4 feeds the outer peripheral ends 2b, 3b of the spiral lines 2, 3, and a high frequency power supply 5 feeds the outer peripheral ends 2c, 3c of the spiral lines 2, 3.SELECTED DRAWING: Figure 1
