DESIGN OF 4 ELEMENT BASED MIMO SLOT ANTENNA

Abstract: A Four element slot based Multiple Input Multiple Output(MIMO) antenna is presented. The antenna elements are planar in structure and designed on a single substrate. The substrate used for antenna design is FR4 epoxy with a dielectric constant of 4.4 the dimensions of the dielectric is 42×25×1.6mm3. The antenna design is optimized to cover various frequency bands from 4.2~7.2GHz making it applicable for WLAN. The proposed antenna is suitable for communication applications. The simulation of the antenna has been performed using High Frequency Structure Simulator (HFSS). The maximum measured gain of the antenna is 1.8dB. The envelope correlation coefficient (ECC) did not exceed .248 in the entire operating band of the MIMO antenna.
