Gain Improvement of A Metasurface for U-slot Microstrip Patch Antenna Array at 5.8 GHz

초록

This paper concentrate on improvement of gain for microstrip planar array antenna. The structure in this project is 2 by 1 microstrip line fed U-slot rectangular antenna array using metasurface, in which the metasurface acts as a superstrate at a small distance. The metasurface is a Mu-nearzero (MNZ) type, an array of 7x7 double-square-closed ring resonators printed on a thin dielectric slab to obtain the maximum gain high at frequency 5.8 GHz array antenna. Frequency 5.8 GHz can be applied to unlicensed WiMAX. The proposed antenna shows improved gain, return loss, and radiation pattern. ? 2018 KIEES.
