Waveguide Bandpass Filter Using Artificial Magnetic Conductor

Novel Artificial Magnetic Conductor for 5G Application

A design of novel bendable Artificial Magnetic Conductor (AMC) structures has been presented in this paper in two selected of frequencies at 5G application. These designs started with a square patch shape and continued with the combination of circular and Jerusalem shape which resonate at a frequency of 18 GHz and 28 GHz. Details of the theory and the structures of AMCs are explained. The refle...

MRI scanner‐independent specific absorption rate measurements using diffusion coefficients

OBJECTIVE The purpose of this study was to measure specific absorption rate (SAR) during MRI scanning using a human torso phantom through quantification of diffusion coefficients independently of those reported by the scanner software for five 1.5 and 3 T clinical MRI systems from different vendors. METHODS A quadrature body coil transmitted the RF power and a body array coil received the sig...

Investigation of a Wearable Textile Monopole Antenna on Specific Absorption Rate at 2.45 GHz

This paper discusses the investigation of a wearable textile monopole antenna on specific absorption rate (SAR) for bodycentric wireless communication applications at 2.45 GHz. The antenna is characterized on a realistic 8 x 8 x 8 mm resolution truncated Hugo body model in CST Microwave Studio software. The result exhibited that the simulated SAR values were reduced significantly by 83.5% as th...

Compact Artificial Magnetic Conductor Designs Using Planar Square Spiral Geometries

Compact spiral artificial magnetic conductors (AMC) have been investigated in this paper. First, single and double spirals are examined to achieve an in-phase reflection at a lower frequency compared to a conventional patch element of the same size. However, these two designs generate a large cross polarization. The cross polarization affects the operating frequency and bandwidth. In order to e...
