Antenna design trabalhos

Hi, I need a creation of an opening and a channel. The idea is to use an old TV () in the animation to make the table, tv and antenna fall bouncing close to each other and stay all embedded end, the screen turns on, the channel name appears on the tv and it moves forward from the inside of the tv, pauses occupying the entire screen and advances up the screen (effect similar to opening netflix, for example) to start the video.

I need a focused research effort that looks at satellite-communication antennas from three angles at once: maximising signal strength and quality, mapping frequency-band usage, and refining antenna design and materials. The outcome should give me clear, data-backed guidance I can hand straight to my hardware team. Scope You will survey current literature and patents, run electromagnetic simulations (HFSS, CST, FEKO or similar), and translate the findings into practical design recommendations. Emphasis is on L-, S- or Ku-band performance; however, if your analysis uncovers a better-suited band, flag it and justify the choice. Deliverables • Concise comparative report (PDF) • Simulation files with setup notes • Performance charts showing gain, VS...

I’m kicking off a multi-phase R&D effort devoted to the design and development of cutting-edge microstrip antennas. The overarching targets are straightforward: boost usable bandwidth while simultaneously lifting signal strength, all without compromising the core advantages of printed technology. Phase by phase, I’ll be iterating from theoretical models through to lab-verified prototypes. You’ll take the lead on concept generation, electromagnetic simulation (HFSS, CST or an equivalent full-wave solver), layout refinement, and hand-over for fabrication. Once hardware comes back, we’ll compare measured S-parameters and radiation patterns against the simulated baseline, fine-tune, and document lessons learned for the next spin. Key deliverables • Sim...

...consumer-electronics device. The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with long lead times and proposing substitutes where sensible • Providing a b...

...optimized for battery life, ruggedized for rain and mud, and small enough to be fit into a broadhead style design for an arrow and light enough to not majorly affect flight path. I would like it rechargeable as well, and a way to turn it on and off to preserve battery life. I’ll lean on your expertise to choose the right chip set, antenna layout, power-saving firmware techniques, and mobile-side integration. A concise mobile demo app (Android or iOS) that plots the device on a map will round out the proof of concept. Once I have a tracker device with size, weight and shape, I will handle the rest of the design in terms of how it affects flight path, delivery and durability. I need a raw design and can take the rest from there. I am looking for a ...

I already have a working ESP32 design in KiCad and need it brought to its final, production-ready form for a commercial product that must clear CE.

I need a miniature sine-wave transmitter board. I will supply the exact antenna footprint and the precise target frequency (it will be somewhere below 100hz, specified down to the decimal). Your task is to design a PCB smaller than 2 cm × 2 cm that generates a clean, low-distortion sine wave, feeds it to the antenna, and runs for at least one month on a single CR2032 coin cell. It has step sweep formula Long-term frequency stability, minimal harmonic content, and ultra-low power consumption are critical. Feel free to use discrete components, a low-power MCU with DAC, a numerically controlled oscillator, or any other architecture that can hit the spec while staying inside the tight footprint and power envelope. Deliverables • Complete schematic and PCB ...

I need a complete mixed-signal design for an eight-channel Bluetooth communication system: four inputs for data acquisition and four outputs for actuation or stimulation. The unit must span a wide frequency range—everything from standard audio bandwidth up into the low-MHz region—while keeping each output capped at 5 V, 5 mA so it remains safe for direct human-facing applications. Because the project will handle live data, the entire chain has to support real-time streaming over Bluetooth Classic; latency has to stay low enough that an audio-rate round-trip remains perceptually seamless. Inside the enclosure, you can split the path however you wish—purely analog front ends feeding ADCs, DSP blocks, then DACs and analog output buffers—so long as the final a...
