Abstract
This shows a wideband antenna with a FSS as a substrate. Initially, a Sim-Shape microstrip patch antenna is designed using an Fr4 substrate having 4.4 permittivity and a height of 1.6 mm with a dimension of 30 x 35 mm square at 4.5 GHz. The simulated result shows a wide band from 3.0 to 6.2 GHz. The bandwidth gain varied from 3.3 dB to 4.2 dB at these frequencies, and the result of a sim-shaped microstrip pattern phenna is improved after the integration of FSS as a substrate. A unit cell of the FSS periodic structure with a 6x7 array is designed using FR4 material. The simulated result shows a wide bandwidth ranging from 3.2 GHz to 6.8 GHz, with a gain improvement of 2.5 dB to 6.5 dB.
