Compact Non‐Planner Inverted Stacked Modified Microstrip Antenna With Enhanced Performance of Ultra‐Wideband Applications
Year: 2024
Type: article
Abstract: ABSTRACT This article introduces a compact non‐planner inverted stacked microstrip antenna tailored for ultrawideband (UWB) applications. The innovative design of the antenna features a folded feed technique combined with a slotted lower patch and an additional parasitic upper patch, showcasing a novel approach to enhancing performance. Compactness is achieved by integrating a shorting wall, significantly reducing the antenna size without compromising performance. The proposed antenna demonstrates exceptional simulated bandwidth (S11<−10 dB) of 11020 MHz (3.6–14.62 GHz), equivalent to 120.9%, and measured impedance bandwidth of 11310 MHz (3.63–14.94 GHz), reflecting a substantial fractional bandwidth of 121.80%. Furthermore, it achieves a peak gain of 9 dBi, making it highly suitable for UWB operations. The combination of its compact size, extensive bandwidth, and stable radiation patterns makes this antenna a highly effective and appropriate choice for UWB technology.
