Rectenna Engineering? Microwave power? Is this possible?

AI Thread Summary
The discussion centers on the feasibility of designing a planar rectenna to power a device using microwaves from a distance of one meter, requiring about a kilowatt of power. The original poster seeks guidance on the design process and cost, emphasizing a lack of knowledge in the area. Responses highlight concerns about safety and legality, questioning the intended application of such technology. Despite the poster's reassurances about safety, the conversation becomes contentious, leading to a moderator's decision to lock the thread due to perceived risks. The topic raises significant safety and regulatory issues surrounding microwave power transmission.

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.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
