DESIGN AND ANALYSIS OF E-SHAPED PATCH ANTENNA TOWARDS ENHANCED GAIN AND WIDEBAND WIRELESS COMMUNICATION

electrical

This study presents the design and analysis of an E-shaped patch antenna with dual slots on a Microstrip Substrate Antenna (MSA). The design incorporates bimodal resonant performance by exciting nearby resonant frequencies. The calculation of antenna gain involves parameters such as antenna width, length, dielectric height, dielectric constant, and orientation angle. The study explores the impact of varying dielectric materials (glass, FR4, vacuum, RT5880, Mica, SiO2) and different heights on the antenna's gain. The results indicate that the antenna achieves significant gains for specific frequencies, demonstrating its potential for widespread wireless communication applications. The designed E-shaped patch antenna exhibits promising characteristics for pervasive wireless communication. Through systematic analysis, the study identifies optimal configurations for maximum gain by considering dielectric materials and substrate heights. The antenna's wideband performance, characterized by low Voltage Standing Wave Ratio (VSWR) and effective band notch filtering, makes it suitable for diverse frequency ranges. Future recommendations include exploring cascaded configurations and antenna array techniques to further enhance gain, responsiveness, and stability at high frequencies.
