Outline of Final Research Achievements |
The aim of this study is to achieve miniaturization and high performance antenna by using magnetic-dielectric nano-composite materials. Small spiral antenna with SiO2 dielectric layers were fabricated. It is noteworthy that the size of antenna is 4×4 mm, less than o.o3λat 2-4 GHz frequencies. To evaluate wideband transmission properties from 0.1-40 GHz, a couple of antenna was faced each other with 30 mm distance and fed by 50 Ω matched wafer probes. High return loss of -10 dB was found at recent wireless communication frequencies of 2-4 GHz.
