چکیده

A method to significantly increase the gain and isolation of a wideband multiple-input multiple-output (MIMO) antenna using metamaterial structures is reported. The proposed medium includes just one wall superstrate, which are fixed in xz xy planes MIMO antenna, respectively. dimensions 13×13×3.5 mm3 at 30 GHz. comparison between simulated conventional microstrip demonstrates good performance environment. corresponding return-loss better than 10 dB over 28–32 GHz for 5G applications. maximum 17.1 GHz, generating enhancement 11.8 with without any structures. (insertion-loss) 36.7 has improved by more 29.4 compared one.

Enhanced Gain Planar Inverted-F Antenna with Metamaterial Superstrate for UMTS Applications

Planar inverted-F antennas (PIFA) are widely used in wireless hand-held devices due to their small-size, moderate bandwidth and radiation patterns. However, the radiation patterns of such antennas degrade when placed very close to a conductive finite ground plane. In this paper, an engineered magnetic superstrate is introduced to enhance the gain of PIFA antennas. The engineered magnetic supers...
