I need a complete design for a flexible, wearable microstrip patch antenna that operates reliably across the sub-6 GHz spectrum for communication devices. My chief concern is bandwidth: the final geometry, substrate choice, and feed configuration must maximise usable bandwidth while keeping return loss below –10 dB over the targeted range. Here is what I expect: • A simulation-validated design file ( CST ) showing S-parameters, radiation pattern, and realised gain. • Clear documentation of substrate stack-up and bending radius limits so the antenna maintains performance when worn. • A concise fabrication guide and, if possible, suggested vendors or processes for producing flexible prototypes. Please attach a detailed project proposal that explains your methodology for bandwidth enhancement—whether through slotting, EBGs, or other techniques—and include any milestones you foresee (design, simulation, optimisation, hand-off). I will shortlist proposals that demonstrate a solid grasp of flexible RF materials and present a clear plan for delivering a wideband, wear-resilient antenna ready for communication-grade integration.

With your wearable sub-6 GHz patch antenna project, I'm confident that my skills and experience in electrical engineering and electronics make me the ideal freelancer for the job. At my core, I specialize in deploying AI-infused technology to solve real-world problems and that includes intertwining it with hardware systems just as your project demands. In terms of designing your antenna, I fully understand the importance of ensuring broad bandwidth while keeping return loss minimal, thus maximizing performance across sub-6 GHz spectrum. My approach to deliver this involves a meticulous methodology with significant milestones including design, simulation, optimization and handoff. These milestones not only ensure task completion, but also offer you an opportunity for evaluation before its communication-grade integration

Hi There! I'm an Antenna design engineer and having relevant experience of designing flexible wearable antenna for bio-medical applications . I will design flexible wearable antenna for sub-6GHz spectrum, I will provid you CST files and technical report of design simulated resultsm S11,, gain, radiation pattern, efficiency, SAR, & FBR (Front to back radiation ratio) (important in wearable antennas) etc I will also show you substrate flexible behaviour effect on antenne performance. (my design was also based on flexible substrate, and was wideband antenna, bandwidth was nearly equal 1Ghz, i used different method to achive broadband bandwidth, & size compactness, ) So Dear Feel free to contact me for more. Thank you

Hi Sir. We can carry out this project for you using CST and provide all the antenna parameters mentioned in the description of the project. About what you expect: • We can provide a simulation-validated design file ( CST ) showing S-parameters, radiation pattern, and realised gain. • We can provide the documentionation you need. • We can address the fabrication of the antenna. For bandwidth enhancement,we can contemplate dual resonance. Constact me to address this in further detail. B/R

I can deliver a simulation-validated, flexible wideband microstrip patch antenna optimized for sub-6 GHz wearable applications. My approach focuses on bandwidth enhancement using slot-loaded patch geometry, partial ground plane, and parasitic coupling to ensure S11 < –10 dB across the band. I will select a proven flexible substrate (e.g., Rogers RT/duroid 5880 or Kapton polyimide) and validate performance under bending conditions. Deliverables include CST design files, S-parameters, radiation patterns, gain plots, and a fabrication guide with vendor suggestions. Milestones: (1) Initial design, (2) CST simulation, (3) optimisation & bending analysis, (4) final documentation and handover.
