Circularly Polarized Dielectric Resonator Antenna for Millimeter Waves

Overview

This repository contains the design, simulation, and analysis of a Circularly Polarized Dielectric Resonator Antenna (CP DRA), created during the Winter Internship Training Program (2023–2024) at MNNIT Allahabad under the guidance of Dr. Anand Sharma. The project focuses on a 5.2 GHz antenna for millimeter-wave applications, demonstrating significant potential for communication and sensing systems.

Key Features

• Circular Polarization: Achieved through a coaxial feed and parasitic dielectric cylinder.
• Wide Bandwidth: An impedance bandwidth of 5.2 GHz and an axial ratio bandwidth of 40%.
• High Gain: Simulated peak gain of 6.5 dB.
• Efficiency: Designed with fabrication simplicity and high radiation efficiency in mind.

Tools and Techniques

• High-Frequency Structure Simulator (HFSS): Used for modeling and optimizing the antenna's performance.
• Parametric Analysis: To achieve the desired circular polarization and gain characteristics.

Applications

• 5G communication networks
• Satellite communication
• Radar systems
• Wireless sensing technologies

Repository Structure
