Hi, I have already designed multiple 4×4 inset-fed patch antenna arrays at different frequencies with excellent performance. I can design your 2.1 GHz 4×4 array on Rogers 4350B (h = 1.524 mm) using an optimized power divider. The design will meet >12 dBi gain, <60° beamwidth, and 100 MHz bandwidth requirements. I can also share previous similar designs upon request.

Hi Client, I have strong experience in antenna design and simulation using CST Studio. Recently, I successfully designed a complex dual-band patch antenna resonating at 19 GHz and 38 GHz and a 1 to 4 Wilkinson power divider using ADS with also fabrication. My Approach: I can complete this project efficiently in three phases: Phase 1: Single Element Design (1 Day) Optimizing the inset-fed patch on Rogers 4350B for the 2.1 GHz center frequency. Phase 2: Feed Network & Array Integration (3-4 Days) Designing the corporate power divider network and integrating it with the 4x4 array layout. Phase 3: Full Optimization & Performance Tuning (1-2 Days) Final CST simulations to ensure the Gain (>12 dBi) and Bandwidth (100 MHz) targets are met. Deliverables: CST Studio source files. Simulation results. Fabrication-ready Gerber files.

I am highly interested in your 4×4 array patch antenna design project at 2.1 GHz using Rogers RO4350B substrate. I have hands-on experience in CST Studio Suite and have already designed and simulated multiple inset-fed microstrip patch antennas and array antennas with corporate power divider networks. In my previous antenna projects: I have achieved excellent impedance matching, with S11 values as low as −42 dB, −43 dB Designed array antennas with high gain (>12 dBi) and controlled beamwidth Successfully met bandwidth targets (~100 MHz) on low-loss substrates like Rogers RO4350B If required, I can share screenshots of my previous CST antenna results (S11, gain, radiation patterns) to demonstrate my work quality. What I will deliver: Complete 4×4 inset-fed microstrip patch antenna design Corporate feed / power divider network Optimized design in CST Studio Suite S-parameters (S11), gain, radiation pattern, beamwidth, and bandwidth results CST project files + simulation results (ready for fabrication or report use) I understand that this antenna requires: Gain greater than 12 dBi Beamwidth < 60° 100 MHz bandwidth Accurate design using RO4350B (h = 1.524 mm) and I am confident in delivering these specifications. Although this is my first project on Freelancer, I have prior experience with similar CST antenna designs, and I am fully committed to providing high-quality and timely delivery. I would be happy to discuss your exact requirements and start immediately.

i have master in telecommunications i can do this work using CST Microwave Studio for the design and simulation of your custom shortwave radio antenna. With my expertise and skills in antenna design, I have the competency to develop the 4x4 array patch antenna exactly as per your specifications: it will be made using Rogers 4350B material, have a height (h) of 1.524mm, and operate at 2.1GHz with an inset-fed patch design, ideal for high gain and decreased beam width. Using my experience, I assure you a gain higher than 12dBi, beam width well below 60 degrees, and a broad bandwidth of 100MHz - all in line with your requirements. My utilization of advanced tools like CST Microwave Studio combined with my adeptness in ADS and MATLAB guarantee a thorough analysis allowing for complete validation of the designed antenna. In conclusion, entrusting me with this project ensures that you get an efficient and optimally performing shortwave radio antenna. Let's build this bespoke communication solution together!
