“…• Step 1-Select the patch shape: Several researchers proposed different patches for design, analysis, and enhanced antenna performance. Previously rectangular, circular (Azam et al 2017), elliptical (Alam et al 2020), T-shaped (Khulbe et al 2016), and many other patch shapes were proposed to operate the antenna in a specific frequency band. Those antennas were designed for different applications, such as medical imaging and diagnosis, security screening, high speed communication system and many more.…”

“…The antenna suggested by khulbe et al (Khulbe et al 2016) showed better gain than the proposed antenna but fails to compact the antenna size and minimize return loss. Similarly, in (Alam et al 2020), the author enhanced efficiency but fails to compact the antenna size, minimize return loss and enhanced antenna gain. All the previous work had some limitations.…”

Modern technology advancement requires a more extensive data rate to convey information more rapidly than ever. Improved bandwidth can satisfy the need for high-speed transmission demand. In order to achieve significantly increased bandwidth for a high data rate communication, the antenna design at the THz band is essential. The microstrip patch antenna is one of the most prominent antennas for THz band applications such future 5G communication systems and advanced wireless communication system. This paper proposed a triangular patch antenna for THz applications where FR4 is used at the substrate as an insulator and Graphene at the patch as a conductor. Moreover, we improve the performance of the proposed antenna by modifying the shape of the patch and ground (GND) layer. We modify the patch shape by cutting the corner edge of the triangular patch. Moreover, the GND layer is modified with horizontally partial ground. The size of the proposed antenna is set to 160×120 µm2. We analyze the performance of the proposed antenna using CST simulation software. Based on the simulation results, the proposed antenna with a modified patch and GND shape shows wide bandwidth of 1.27 THz and minimal return loss of -33.22 dB at a resonant frequency of 2.28 THz. Additionally, the gain and efficiency of the suggested antenna show good improvement. Therefore, the proposed triangular patch antenna with a modified patch and GND shape is expected to be suitable for high-speed THz applications.
