Title:
アンテナおよび当該アンテナを備えた装置
Document Type and Number:
Japanese Patent JP3664721
Kind Code:
B2
Abstract:
The present invention provides an antenna in which, on a dielectric substrate 1 having a back face on which a grounding conductor plate 14 is disposed, a plurality of conductor elements 12 are arranged in a matrix of rows and columns. Each of the dielectric elements 12 has a size which cannot function as an antenna. Above the conductor elements 12, a connecting element 13 overlapping two adjacent conductor elements 12 is disposed. Among the connecting elements 13, some cause the conductor elements 12 on both sides to be in a conductive condition, and others cause the conductor elements 12 on both sides to be in a non-conductive condition. The switching between the conductive and non-conductive conditions between the conductor elements 12 can be dynamically performed by a switching element.
