Abstract Space-fed array comprising of Wallmount Rangehoods E-shape or U-slot cut rectangular microstrip antennas using the modified feed designs are proposed for higher gain and wider bandwidth.Modified feed optimally illuminates the edge space-fed elements to achieve a maximum gain.Amongst the two space-fed array variations, 7 x 7 E-shape space-fed array, excited using the feed comprising of gap-coupled and stacked E-shape patches provides bandwidth and gain of 2.085 GHz (48.97%) and Blood Pressure Kits 18.

5 dBi, respectively.The antenna exhibits broadside radiation pattern across the complete bandwidth.An experimental validation has been carried out for the simulated results that show a close agreement.
