Abstract: This
paper presents a novel elliptical coplanar waveguide (CPW)-fed slot antenna with
multiple circular rings tuning stubs designs targeting the 3.1-10.6GHz band. The
antenna is comprised of multiple circular rings tuning stubs that excite
elliptical slot aperture. Antenna prototype has been simulated, fabricated and
experimentally tested; it is being fed by a CPW Technique, exhibiting a very
satisfactory behavior throughout the 7.5GHz of the allocated bandwidth in terms
of impedance matching radiation efficiency and radiation
pattern characteristics. Measured impedance bandwidths of beyond 208% will be
presented.
