Assuming the antenna is a perfect 50 ohms, what would the values of L* and C* be? I am just trying to figure out what to order for parts to start with. The VSWR <2.0 typ. at center. Also I assume I will need to build 2 amps, 1 for each oscillator, or can I tie them both into the same amp...
vfone, wow, thanks so much, this is awesome, hopefully it works :) Can I use a simple straight piece of 25cm wire for the antenna? If so what would L* and C* be? Do you have any guess on how much better this circuit and antenna will be over the current design (2x, 10x, 100x)?
I took some EE classes in college and have built small circuit boards before, I have a breadboard and wiring, resistors, etc. I have no doubt I could build it, designing it on the other hand :) that information has long since leaked out of my brain...
If someone could do me a huge favor of...
Thanks for your input biff. I don't know what the receiver antenna looks like. How would I create and connect a metal ground plane, just put a metal plate under the PCB and connect it to ground?
Thank you very much for the help :) vfone as I said there are no design limitations, I could add a 25cm antenna if needed. What I don't understand is how I would add it, where do I connect it? Just solder it too the loop? Should I disconnect the loop then? Use one antenna for each loop...
Hello, I would like to modify the antenna on this circuit board to extend the broadcasting range of the antenna. I have little experience in antennas and am seeking the wisdom of this board. There are no restrictions on design, my first thought is to add a whip antenna, but I'm unsure if this...
