This article presents a miniaturized three‐dimensional super wideband antenna with filtering capabilities. A conventional rectangular patch antenna has been modified by truncating its corners with semi‐circles and a trapezoidal shaped partial ground plane is utilized to achieve super wideband performance. The planar design is later extended to a 3D design with the addition of three dielectric cuboids in the radiator. The cuboids are inserted at low current density regions within the operating range to achieve miniaturization compared to the planar antenna. The impedance bandwidth of the 3D antenna is ~17.55 GHz, measured from 2.45 to 20 GHz. The filtering capabilities are achieved by means of an upside‐down T‐shaped resonator introduced in the center of the patch and two U‐shaped slots etched from the patch. In total, three interfering communication bands are rejected, WiMAX (3.2–3.8 GHz), IEEE 802.11/WLAN (5.17–5.33 GHz), and ITU (7.7–8.5 GHz). The proposed antenna is miniaturized as it merely has an overall size of 0.20λl × 0.19λw × 0.011λh mm3 (corresponds to 2.45 GHz) compared to the relevant literature. The design has been analyzed using an equivalent circuit model, fabricated and measured for validation. The simulated and measured results are found well in agreement. [ABSTRACT FROM AUTHOR] |
