Concatenated Metamaterial Surfaces Making 5G Mobile Antenna Signals Strong

In order to enhance the power of the received signal between the 5G transmitting and receiving antennas, three structures are proposed based on the use of metasurfaces. Structure 1 is a non-tilting metasurface between millimeter-wave antennas at port 1 and port 2. Structure 2 lays the tilted to the right, non-tilting and tilted to the left metasurfaces from the left through the center to the right areas on the same layer. Structure 3 places structure 2 over another of the same kind. Experiments on structure 1 as the building block and structures 2 and 3 as augmented metamaterials give increment of around <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$7 \text{dB}, 9 \text{dB}$</tex> and 14 dB in the level of the received signal. Considering volumes as small as <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$7.0 \times 7.0 \times 3.0 \text{cm} 3$</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$21.0 \times 7.0 \times 6.5 \text{cm} 3$</tex> for structure 1 and structures 2 and 3, respectively, it will turns out to be useful in making 5G antennas deterring fast path loss.
