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 (????????????(????) = 0.02, ???????? = 4.3).
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 |????11| < −10 ???????? 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 modes.
