Keywords:
Ring patch antenna, Frequency selective surface (FSS), ISM bandAbstract
This article presents the design of a metasurface design using a bandstop reflector based on Frequency Selective Surface (FSS) which is used a metasurface to work with a planar ring antenna to enhance the gain that is operated along the ISM band of 2.45 GHz and 5.8 GHz. The both structures design on FR-4 substrate with thickness of 1.6 mm and dielectric constant of 4.3. The planar antenna and the metasurface have the size of 30 mm×45 mm and 82 mm×82 mm, respectively. The antenna located above the metasurface with the length of 12 mm. The simulation results of gain
at 2.45 GHz and 5.8 GHz are 5.66 dBi and 9.02 dBi, respectively which radiation pattern of an antenna is unidirectional beam.
