Abstract
In this study, a compact crescent‐shaped microstrip patch antenna is proposed for super wideband (SWB) applications. The antenna consists of a rectangular, slotted partial ground plane and a crescent shape radiating patch to cover wider frequency band than the ultrawideband. The proposed antenna is fabricated on an FR4 substrate and is fed with a 50 Ω microstrip feed line. The substrate has a thickness of 1.60 mm with the relative permittivity of 4.4, and a dielectric loss tangent of 0.02. The proposed antenna has a compact size of 32 mm × 22 mm with the electrical dimension of 0.27λ × 0.18λ. The simulated results agree with the measured results. The result shows that the proposed antenna achieves reflection coefficient less than −10 dB (VSWR < 2) from 2.5 GHz to 29.0 GHz that is a 168.25% fractional bandwidth with 11.6:1 bandwidth ratio. The proposed antenna achieves the durable omnidirectional radiation pattern throughout the operating band with 6.10 dBi of maximum gain. The bandwidth dimension ratio of the presented antenna is 3462.02. As the antenna shows the SWB characteristics, it can be used in the high fidelity short pulse applications. The proposed antenna can be used in S, C, X, Ku, K, ISM, Wi‐Fi, WLAN, WiMAX, and MVDDS wireless communication systems.
