Abstract:-In this article, a composite wide slot antenna
with crescent-shaped tuning stub and a hybrid parasitic element is analyzed,
which is printed on the FR-4 epoxy substrate (
). The capacitive coupling between elements,
overlapping of excited modes and impedance bandwidth of the antenna are amended
by adjusting the size of the composite slot and tuning stub. From simulation
outcomes, the simulated impedance bandwidth of this antenna is 141.15 % for
which
resonates at five frequencies 1.1, 1.73, 3.02, 4.63 and 5.43 GHz. The bidirectional
pattern has been obtained at lower frequencies (1.18 GHz, 2.38 GHz) whereas
distorted patterns are noticed at the higher frequency (5.25 GHz) due to the
existence of higher order models.
