| Outline of Final Research Achievements |
With progress in communications systems, the deterioration in the communication efficiency, which is caused by interference of malicious electromagnetic waves, becomes a serious issue. Fortunately, this deterioration is overcome if an antenna acting as an input/output of the communication system is electromagnetically functionalized. Such an antenna is called Anti-interference Antenna: AI-ANT. It is noted that there are some AI-ANTs that radiate a linearly polarized wave, however there are few circularly polarized AI-ANTs due to difficulties in the antenna fabrication. The purpose of this project is to overcome the fabrication difficulties and create a circularly polarized AI-ANT. It is emphasized that this antenna is made of metamaterial atoms and has a thin plane structure. The antenna is abbreviated as AI-MetaANT.
