Engineering - Communication Technology

In this paper, a novel compact designs of rectangular shaped antenna are proposed. The proposed antenna consists of rectangular shaped patch of Lxp=11.86 mm by Lyp=9.06 mm. The antenna consists of four circled concave on four corners of rectangular patch. All simulation was done by using Rogers RT/duroid 5880 substrate material having dielectric constant ε_r= 2.2 and dielectric loss tangent tan δ =0.0009.The designs were analyzed by Finite Element Method (FEM) based HFSS™ Electromagnetic simulator software. Return loss, VSWR plot, smith chart and radiation pattern plots were observed and plotted for all designed antennas. The proposed antenna operates on X-Band (8-12 GHz) frequencies.

Zielsetzung und Themenschwerpunkte

This paper presents two novel compact designs of rectangular shaped antennas for X-Band applications. The main objective is to achieve a wideband dual-frequency response in the X-Band (8-12 GHz) frequency range. The antennas are designed using a rectangular patch with four circled concave slots on the corners. The paper focuses on the design, simulation, and analysis of these antennas using the Finite Element Method (FEM) based HFSSTM Electromagnetic simulator software.

• Design and simulation of compact rectangular shaped antennas for X-Band applications
• Achieving wideband dual-frequency response in the X-Band (8-12 GHz)
• Analysis of antenna performance using FEM based HFSSTM software
• Evaluation of return loss, VSWR, and radiation patterns
• Comparison of antenna parameters for different configurations

Zusammenfassung der Kapitel

The paper begins by introducing the importance of wideband and multiband antennas in modern wireless communication and RF communications. It highlights the advantages of microstrip antennas, including their robust design, compactness, and performance. The paper then presents two different antenna configurations with wideband dual-frequency response in the X-Band. The first configuration features four circled concave slots on the corners of the rectangular patch, while the second configuration incorporates a slit in the patch. The paper provides detailed simulation results for both configurations, including return loss, VSWR, radiation patterns, and antenna parameters. The results demonstrate the effectiveness of the proposed designs in achieving the desired frequency response and performance characteristics in the X-Band.
