A printed ultra-wideband antenna of compact size (0.36 λ_L × 0.31 λ_L) that delivers bandwidth (S₁₁ ≤ −10 dB) of 2.64–9.36 GHz (112%), with triple notches at 3.28–3.84, 5.08–5.44 and 5.62–6.06 GHz to reject contemporaneous wireless interventions such as WiMAX and WLAN is reported in this article. The proposed antenna performance is established by both simulation and experimental measurement. The antenna affords gain variation from 2 to 5 dBi, radiation efficiency of 80% on an average, linear transfer function and non-varying group delay response in its pass bandwidth while significant deviations are observed in the three notch bands. Bi-directional E-plane and non-directional H-plane patterns are testified in the antenna pass band. Antenna bandwidth is also measured in proximity of soil, wood and glass by keeping metal plate at bottom where an unaltered bandwidth response is observed that justify its capability to work for surface penetrating application.
