Abstract: She will present the latest studies in microwave polarization antennas. These technologies could be applied to detection of environment, geography, and resources. First, recent technologies will be introduced about microwave circular polarization plane antennas. Conventional plane (stripline) antennas are restricted in characteristics in bandwidth and directivities. It causes big scale of arrays with large number of unit antennas. Then, novel approaches by the authors are presented. The fundamental point is about the structure of stripline resonators. The second is the configuration of four antennas in an array. Orthogonal arrangement and parallel feeding are given here. The third is a novel configuration of feeding routing wires to reduce multiple reflections found at connecting circuit-points of circuit points. The others include novel structure for reduction of cross-sectional radiation and increase of directivity and gain. Finally, the applications to practical systems are presented using extremely wideband and effectively minimized configuration of plane antenna arrays.
Brief Biography of the Speaker: Yumi Takizawa received the Ph.D. degree from the University of Tokyo in 1994 after the BS degree from the Shinshu University in 1984. She joined in the Communication System Lab., OKI Electric, Tokyo. Then she joined in the Institute of Statistical Mathematics (ISM) as an associate professor in 1995. She has been engaged in experimental study of neural systems in weakly electric fish at the University of Virginia, USA, 1998 and 2000. The Best Paper Prize of Neurology’12, WSEAS/NAUN was awarded to this study, July 2012.
