| Summary: | 碩士 === 大葉大學 === 電機工程學系 === 97 === This thesis proposes a miniaturized frequency selective surface design for wireless communication devices. This miniaturized frequency selective surface has a well transmittance in the specific communication band, a good shielding effectiveness out of this band, and an excellent resonance stability performance with respect to different polarizations and angles of incident plane-waves. A band-pass shielding enclosure assembled by this miniaturized frequency selective surface only makes a slightly influence on the internal antenna impedance and antenna patterns.
This thesis discusses the procedure for designing miniaturized frequency selective surface by simulation first. Based on the simulation, this miniaturized frequency selective surface indeed achieves the performance requirements. Then we created and examined prototype of the miniaturized frequency selective surface. Both the simulated and measured results obtained demonstrate the claimed performance.
