— 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.
