Abstract

This letter presents a new design for a circularly polarized square slot antenna
with an enhanced impedance bandwidth. The antenna structure includes
a pair of inverted-L
grounded arms, around two opposite corners which
can result the CP bandwidth
of
the proposed antenna at 5.14-7.78 GHz
.The designed Circularly  Polarized Slot Antenna with size 25 mm (length) ×25mm (width) ×0.8 mm (height) is greatly
improved for achieving a significantly enhanced impedance bandwidth
of 2–13
GHz with VSWR  ≤  2.
The simulation results have been
showed that using inverted-L
grounded arms,
circular and strip patches are increasing the CP bandwidth and reduce the size
of the proposed antenna.
