Antenna Gain Enhancement with Magnetic Metasurfaces

Homogeneous and inhomogeneous electromagnetic metasurfaces are designed to enhance the gain of patch antennas operating at 10 GHz. The metasurface consists of metallic split ring resonators, which can be fabricated with conventional printed circuit board technology on the top of a low loss substrate material. The metasurfaces are mounted above the patch antennas. It is shown by simulations and measurements that the gain of the metamaterial antennas at the operating frequency of 10 GHz have a threefold gain increase compared to the standalone patch.
