Abstract

In this study, an X-band band-stop frequency selective surface (FSS) consisting of aligned finite length periodic conductive cylindrical fibers embedded in a dielectric host material is designed, manufactured, and electrically tested in the frequency range of 2 to 18 GHz. Furthermore, an equivalent circuit model is developed to estimate the electrical characterization of the band-stop FSS. Finally, the transmission results obtained from simulations are experimentally validated using a free-space setup. Moreover, a quasi-isotropic multilayer band-stop FSS is recommended to design a polarization-independent FSS.

Abstract

This study covers the design, manufacturing, and experimental electrical tests for a novel three-dimensional (3-D) band-pass frequency selective surfaces (FSS) containing continuous and discontinuous conductive fibers. The proposed FSS is designed based on 3-D numerical simulations to operate in the frequency range 8-12 GHz with resonant frequency at around 9.5 GHz. An equivalent circuit model of the proposed FSS is constructed to predict and understand the electrical behavior of the structure. Moreover, the experimental result of a fabricated prototype is obtained to demonstrate the validity of both the simulation results and the equivalent circuit model prediction. Furthermore, a quasi-isotropic multilayer FSS having fibers with different orientations is considered to provide a band-pass filter performance under various incident angles for both transverse electric (TE) and transverse magnetic (TM) polarizations.

Abstract

In the presented study, the design and electrical simulations of a noval planar inverted F antenna (PIFA) with plane ground surface supporting both Wi-Fi and Bluetooth technologies were performed. The physical parameters of the noval antenna model were obtained for the 2.47 GHz operating frequency, and the antenna was positioned in a smartwatch with dimensions of 3cm x 3cm x 1cm. The variation of reflection coefficient due to frequency for PIFA and smartwatch was investigated and it was seen that the smartwatch model does not cause a significant change in antenna performance. Then, 2D and 3D directivity patterns are obtained and compared for three different steps of the design that is analysed on an adult human hand. [ABSTRACT FROM AUTHOR]
