A simple novel compact wideband directive metasurface (MS) enabled antenna is proposed. Two same dimensions of edge fed slots are used to excite the MS layer which is made of a periodic arrangement of a rectangular loop‐based unit cell. An optimised resonant slot fed at the edge with a simple micro‐strip line together with the epsilon very large MS layer exhibits wideband behaviour. The antenna yields a bandwidth from 5.89 to 6.6 GHz for a voltage standing wave ratio < 2 (12%) compared with a measured fractional bandwidth of 14%. A maximum broadside directivity of 10.5 dBi has been achieved. Simulated efficiency is more than 87%. The measurements characteristics of this antenna are in agreement with simulated results.
