Rectenna Engineering? Microwave power? Is this possible?

Click For Summary

Discussion Overview

The discussion centers around the feasibility of designing a rectenna capable of receiving microwave power from a distance of about one meter to power a device. Participants explore the technical aspects of rectenna design, safety concerns, and the potential costs involved.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant inquires about the possibility of designing a planar rectenna with an area of one square meter to receive approximately one kW of power from a microwave emitter.
  • Another participant expresses concern regarding the safety and legality of the proposed application, questioning the intent behind the request.
  • The original poster insists that their inquiry is purely theoretical and not intended for practical application, seeking information on design and cost.
  • There is a back-and-forth exchange regarding the context of the inquiry, with one participant emphasizing the need for clarity on the application to address safety concerns.
  • The discussion concludes with a participant stating that the topic is too dangerous, leading to the thread being locked.

Areas of Agreement / Disagreement

Participants do not reach a consensus. There is disagreement regarding the safety and legality of the proposed project, with one participant expressing concern while the original poster maintains that their inquiry is harmless.

Contextual Notes

The discussion lacks detailed technical specifications for rectenna design and does not resolve the safety and legal implications of using microwave power in this context.

I want to power a device using microwaves. The microwave emitter will be about 1 meter away. I want the rectenna to be about a square meter in area and planar (not a dish). The rectenna will need to pass on about a kW of power.

Is this possible? How do I design a rectenna like that? How much would it cost? I know nothing about this, so thanks in advance if you can point me into to the right direction.

Thanks!

Lordy son, what in the world are you up to? You do understand that what you are asking about is dangerous and illegal on the surface of it, right? What is the safe and legal application that you have in mind?
 
Hey thanks for the reply

I'm not going to do anything dangerous haha. I'm just wondering if it's possible to design a rectenna the way I want it. Do you know anything about rectennas?
 
Yep. But you did not answer my questions. What is the context of your posted question?
 
Lordy man
why are you being so difficult?

I answered your questions. You asked me what my application was, and I answered that I wasn't going to do anything dangerous. I just wanted to know if it was possible, how much it would cost, and how such a rectenna must be designed. The context is that it would be to power a device, but I'm not actually going to do it. I just want to know what's involved.

Can you help me or not?

No sorry. Too dangerous on the face of it. Thread locked.
