Abstract<\/b><\/h5>\n
Antennas offering wide bandwidth, high gain and efficiency are essential to terahertz (THz) wireless communication <\/span>systems and has gathered significant attention in antenna research. <\/span>This paper introduces a compact, high-gain, ultra-wideband <\/span>(UWB) microstrip patch antenna tailored for THz applications, <\/span>along with its performance analysis. The proposed antenna has <\/span>an elliptical patch with a pi shaped slot and is excited by a tapered <\/span>feedline. An elliptical patch antenna incorporating a pi-shaped <\/span>slot is introduced for the first time in the terahertz THz spectral <\/span>region, demonstrating the ability to simultaneously achieve substantial <\/span>size miniaturization, wideband performance, improved <\/span>impedance matching, and enhanced gain. The antenna structure <\/span>was designed and optimized for improved performance using CST <\/span>Microwave Studio (MWS) version 2018. A Rogers RT\/duroid 5880 <\/span>substrate was used for antenna design, featuring 6 \u03bcm thickness, <\/span>2.2 relative permittivity, 0.0009 loss tangent, and 120 \u00d7 80 \u03bcm\u00b2 <\/span>planar dimensions. The proposed antenna demonstrates strong <\/span>performance characteristics with a wide impedance bandwidth <\/span>of 3.41 THz (5.01\u20138.42 THz), high gain of 7.906 dB, radiation efficiency <\/span>of 77.83%, and low return loss of \u221243.57 dB, with consistent <\/span>VSWR across the entire frequency range. The surface current distribution <\/span>as well as the input impedance of the pi-shaped slotted <\/span>antenna are also favorable. All the simulation results suggest that <\/span>the proposed small size pi-shaped slotted elliptical patch antenna<\/span><\/h5>
can be a suitable candidate for high-speed 6G wireless communication applications in the THz band.<\/span><\/h5>\n
