| Outline of Final Research Achievements |
Multi-polarized metamaterial antennas are created on the basis of theoretical investigation and confirmed by experimental work. The following points are clarified: 1) the antenna mechanism, 2) the radiation characteristics for a low-profile antenna structure, and 3) the antenna operating bandwidth. It is found that the metamaterial spiral and loop antennas operate across a bandwidth of more than 10%, radiating right- and left-handed circularly polarized waves, and horizontal and vertical linearly polarized waves.
