Dual-Band Microstrip Patch Antenna for Wi-Fi Applications (2.4 & 5 GHz)

Project Description

We are seeking a freelancer to design and simulate a dual-band microstrip patch antenna that operates efficiently in both the 2.4 GHz and 5 GHz Wi-Fi bands.

This project is fully simulation-based. The final result should include all simulation files and a clean, technical report.

🎯 Objectives:

• Design a dual-band microstrip patch antenna with:
  • Operational frequencies: 2.4 GHz ± 50 MHz and 5.2–5.8 GHz
  • Substrate material selection (FR4 or Rogers preferred)
  • Compact size with reasonable isolation between bands
  • Return loss better than –10 dB in both bands
  • 50Ω impedance matching
• Perform full-wave simulation, including:
  • S11 parameter plots for both bands
  • Radiation patterns for both bands
  • Gain and efficiency at each band
  • VSWR and bandwidth analysis
• Document the full design process, including:
  • Design rationale
  • Parameter optimization
  • Geometry sketches with labeled dimensions
  • Comparison of performance at both bands

📦 Deliverables:

• Simulation model files (CST, HFSS, FEKO, or similar)
• Exported results:
  • S11 vs frequency plots
  • 2D and 3D radiation patterns
  • VSWR plots
• Design report (5–8 pages) including:
  • Design overview
  • Results summary
  • Discussion of trade-offs and practical considerations
  • Image-based layout of the antenna with dimensions

🛠 Suggested Tools:

• CST Microwave Studio
• HFSS, FEKO, or any full-wave 3D EM simulator
• Optional: Python/MATLAB for post-processing or plotting

🕒 Timeline: 10–14 days total

📥 How to Apply:
Applicants must include:

• A sample of a previous patch antenna project (image or report)
• Simulation software they will use
• Confirmation they are comfortable delivering the project independently
