Abstract |
In order to enhance the power of the received signal between the millimeter-wave 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 7 dB, 9 dB and 14 dB in the level of the received signal. Considering volumes as small as 7.0 7.0 3.0 cm3 and 21.0 7.0 6.5 cm3 for structure 1 and ? ? ? ? structures 2 and 3, respectively, it will turn out to be useful in making millimeter-wave antennas deterring fast path loss. |
