Textile waveguide sheet with Artificial Magnetic Conductor structures for body centric wireless communication

摘要

This paper presented a textile sheet-like waveguide that incorporates Artificial Magnetic Conductor (AMC) structures. The aim is to investigate the possibility of a textile conformal waveguide in improving transmission between antennas when placed beneath them. Investigations were carried for small and belly size AMC waveguide sheets made of denim fabric. Both of the waveguide sheets exhibit promising results with S21 transmission of approximately −10dB at 5.8GHz resonant frequency. Transmission between two dipoles was enhanced with the introduction of AMC waveguide due to its inphase reflection characteristic. Promising results give future possibilities for practical realization of conformal AMC waveguide jacket made purely of textiles.
