3–3.5 GHz Rectangular Patch Antenna

@leonidye

Hi, I am very interested in your microstrip patch antenna project. I have experience designing and optimizing RF antennas for ISM, Wi-Fi, GNSS, and mid-band wireless applications using CST Studio Suite, HFSS, and ADS, with a strong focus on impedance matching, bandwidth optimization, and radiation performance. For this project, I will design a rectangular patch antenna operating across the 3.0–3.5 GHz band, optimized for array integration and U.FL-fed operation. The deliverables will include a fully documented CST model with all material properties, boundaries, ports, and simulation settings, along with S11, VSWR, gain, efficiency, and radiation pattern results. I will also provide a concise design report explaining the feed method, substrate selection, matching approach, and bandwidth-enhancement techniques used to achieve the required performance. Before finalizing the design, I will validate that the simulated −10 dB impedance bandwidth covers the target frequency range and ensure the CST project is fully compatible with CST Studio Suite 2020 or later. I would be happy to review your previous antenna design and discuss the most suitable substrate and feeding technique to maximize bandwidth while maintaining stable radiation characteristics. Regards,

Hi There! I'm Professional Antenna design engineer using CST Studio & well expereinced on 5G-mid-band & WLAN patch works, I will surely design rectangular microstrip patch antenna that will operate across 3000MHz to 3500 MHz, and will be perfectly matched S11 in entire band will be less than -10 dB and will be more improved one then your mentioned criteria. i will provide you CST File with technical report of s11 parameters, VSWR, Radiation Patteren, gain & efficiency etc.. feel free to contact me for more. Regards: Fahad.

Hello, My name is Bharghav, and I have 10 years of experience in electrical engineering, specializing in antenna design and RF simulations using Matlab and CST Studio. I understand you need a 3–3.5 GHz rectangular patch antenna for an AoA direction-finding array. I will model the microstrip antenna in CST, optimizing the substrate and feed line to achieve a -10 dB impedance bandwidth of over 500 MHz. I will deliver the fully defined CST project file, S-parameter and VSWR plots, and a detailed design report explaining the matching techniques.
