Abstract
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
