Abstract: This paper presents the prototype and simulations of a compact rectangular microstrip patch antenna for ultra-wideband applications. The proposed antenna is printed on FR4 (Flame Retardant) substrate with relative permittivity of 4.4, dielectric loss tangent of 0.0024 and the dimensions of 57 × 25 × 1.57 mm3 . The radiating patch of the antenna is loaded with two rectangular stubs along its upper and lower edges and an equilateral triangular notch is truncated from the reduced ground plane to achieve optimum results in terms of bandwidth and reflection coefficient. It is fed along the centerline of symmetry by 50Ω microstrip feed line. The simulated return loss characteristics show that the proposed antenna has a capability of covering the wireless bands from 0.17GHz to 7.25GHz with impedance bandwidth of 7.08GHz and exhibits a peak gain of 5dB at 7.25GHz which is acceptable for UWB systems.
