I'm looking for someone with experience in antenna design to construct a unidirectional transmitter to send digital pulse type signals via tuned inductive resonance (from one antenna to its match).
Any thoughts on this?
This being the antenna to match:

 

What do you mean by antenna? Tuned inductive resonance is term normally used with coupled (magnetic fields) coil inductors , not with antennas that transmit EM waves as a free space electrical energy propagation transducer.

 

To electromagnetically couple to this component via rf

 

Couple to what device, at what frequency, at what power and at what distance?

 

To send a pwm signal to the componet

 

The Component pictured is a Choke or an Inductor,
and is specifically designed NOT to radiate, or receive, like an Antenna.

It is possible to make a resonant circuit that would use a shielded inductor, the value in Henries, mH. uH. nH is what is needed.
Determine the resonance of the circuit that includes the shielded inductor and it's impedance and how far this circuit needs to go. 3 feet?
Is there an LtSpice model? Often we find small amounts of resonant frequency on power rails and is useful for feedback to an oscillator amplifier.
it is not always obvious that the feed point can be power rail. With wireless the pathway to a remote oscillator is located close to the unspecified component, I2C plug n play is becoming more popular as a synchronous protocol people like not having wires while charging lots of batteries.

more specifically, it's a shielded inductor, designed to radiate less than your average surface-mount inductor.

My first thought i to contact "CoilCraft" to see if they have such a device in their vast product line.
But then it seems that there is a lot more involved if a whole transmitter is to be designed.

So I suggest that the thread starter needs to provide more information about the goal of the project, as has already been asked by others.
This forum does provide access to a great number of talented and educated folks, but many of them are limited in their abilities to read what others have hidden in their minds. Thus adequate explanations are a great benefit.

 

Welcome to AAC.

It is important to provide more details about why you want to do this—that is, what’s the application?

Based on your question you seem to be lacking some basic knowledge about electromagnetics and the differences between the E and B fields. Considering this, your ”solution” may be unsuited to the problem you intend it to solve.

Could you describe what you expect this to do?

 

There are quite a few papers and articles about wireless magnetic data transfer. Even the British Railway system was doing it back in 1950. So here is a lot of both theory and practical information available. But as for wireless magnetic power transfer, that is what I consider a poor choice because it is always less efficient than a well designed direct connection. In addition, much of the loss is due to non-captured transmitted power. THAT radiated power can certainly,at best, cause interference with other electrical systems, and at worst, cause damage to living creatures, including humans.

 

The cheapest is to buy 10-15 mm module realizing everything factorymade, the 1 km Nordic NRF024L costs cheapest 1 USD and LORA(TM) cheapest about 3 USD (up to 3 km, or more expensive versions up to several tens of km). Logically, NRF is faster and Lora is slower. And one battery may stand 3 years once a minute telegrams with Nordic and slight less than one year with Lora. I use both for supervision data telemetry.
If any directivity is mandatory, the Cantenna is ultimate solution.

 

The "Cantenna" that I am aware of is a high power oil filled, 50 ohm dummy load that was sold by the Heathkit company for many years. So evidently somebody else is using that name for a quite different product now.

 

Hello,

The following page has a couple of links to cantennas:

What we have here is a condition where two different groups have used the came name for an item without the different items being related. The earlier use was for an RF load resistor package intended for use in testing HF radio transmitters. At that point the name was probably copyrighted by the HEATH company, the produced of the "CANTENNA" Dummy Load product, back in the 1960's era. Many years later, with the development of microwave experimenter projects, the use of cans as portion of antennas for different wavelengths evidently gave way to the re-use of the name for another product.
Hence my puzzlement.
