Wideband RF Energy Harvesting Antenna Design

I need a Fto based transparent compact patch antenna modelled in CST Studio Suite that can efficiently collect ambient RF power across a very wide band. The end use is pure RF energy harvesting, so instead of targeting a narrow communication band I am after the broadest practical frequency coverage you can squeeze out of a single‐layer or multilayer patch structure without driving size or complexity through the roof. Key requirements • Frequency coverage: “RF frequency wideband” – essentially as wide as we can get while keeping reasonable overall dimensions and good impedance matching. Please propose the exact limits you can reach and back them up with simulation data. • Polarisation: I am open to linear, circular or even dual; pick whichever helps you achieve maximum harvested power and bandwidth. • Platform: All work must be carried out in CST. I need the native .cst file with all parameters left editable, plus exported drawings so I can send the board straight to fabrication. Deliverables 1. Optimised CST model of the patch (including substrate definition, feed, and any matching / bandwidth-enhancement tricks you choose). 2. Simulation report: S₁₁ curve, gain, efficiency, radiation pattern plots across the band, and estimated harvested power density at 1 m. 3. Short design note explaining material choices, bandwidth-widening techniques, and any trade-offs you made. Acceptance criteria • |S₁₁| ≤ –10 dB over at least 50 % fractional bandwidth (or better if you can). • Peak gain ≥ 3 dBi somewhere inside that band. • All files open and run in CST 2018 or later with no errors. If you have previous broadband or energy-harvesting antenna work, feel free to mention it when you respond. I’m ready to get started as soon as I see a sensible bandwidth proposal. I have shared research paper for my design, the design should be done according to the model configuration give in paper.
