Esquilo's latest activity

It all depends on what you want the the interference patterns need to be. The best design will depend on the wanted spatial pattern. You...

So, yes, as far as the angular range to operate is concerned, the desirable limit would be 5 degrees, but it's difficult to achieve...

Good morning,@sophiecentaur I will use the same transmitter for all the cavity patches and I will vary the phases of all the antennas...

@sophiecentaur Thanks for your reply. So, yes, the receiver question isn't very important at this point, since it can be made of a wide...

The "beats" you refer to are only beats when your receiver looks at the vector sum of all the signals. You could look at the process in...

@berkeman @.Scott @sophiecentaur @tech99 @renormalize Good morning, here I am again, I had created a new thread on the same topic but it...

This is all at a very low frequency so I feel that all that could be done with software (Software Defined Radio). None of that beastly...

@berkeman @.Scott Yes, I've checked more closely these past few hours, and the theremin solution is the most efficient. I'll definitely...

I wasn't going to get into his theremin design. But if we do, why would we use a phase array instead of two or three directional...

Yikes, you may be missing a minus sign or something there... :wink: From a Google search on VDE Level B at 3m test distance: So you...

A standard Theremin uses 3 oscillators, two working at about 260 kHz and one at 450 khz. Nothing oscillates at nearly a gigahertz. See...

yes I should use maybe more than two receivers, I could make a system similar to metal detectors but it would be too difficult, and as...

You need two radio receivers. Each receiver will include an antenna and some circuitry. The channel width is described in Hz. So, if...

57 and 47 dbm at 3 meters, yes you are actually right with square signals I have many harmonics and therefore a lot of noise I will have...

What is your planned transmit power in dBm? What is the maximum allowed RF level detected for Germany's Level A and Level B tested at 3...
