The Federal Communications Commission (FCC)has adopted a new rule, on April 23, 2020, making 1200 Megahertz of frequency spectrum in wireless fidelity (Wi−Fi) 6 GHz frequency band (5.925−7.125) GHz for the unlicensed user. Based on the announcement, a cylindrical shaped antenna resonated at 6.5 GHz frequency is proposed for Wi−Fi applications in the routers through this work. A material named FR4−Epoxy having dielectric constant 4.4 and loss tangent 0.02 is used in substrate layer that builds up the antenna compact enough. The antenna with a dimension of length 60 mm and radius 3.55 mm at all is manifested in a tiny cylindrical shape and consequently, can be a compatible candidate for implementation in wireless routers conveniently. The behaviour of radiation characteristics of cylindrical shaped antenna is analyzed. Circular polarization of radiation surrounding the antenna, a very significant characteristic of an antenna to be applied for Wi−Fi applications, is realized by the proposed antenna. The value of gain, wide bandwidth cohering across the frequency band, minimum value of reflection coefficient and voltage standing wave ratio, high radiation efficiency, and all the other better performances pledge that the antenna is apposite to the Wi−Fi applications.
