So I recently picked up 40 of 10.525 GHz Microwave RADAR transmitters:
I opened up one out of curiosity and had something like this (image attached) . I noticed some parts of the PCB aren't even connected to anything. How do the different shapes and sizes of the PCB interact with each-other...
I had an idea of building an FM receiver that is powered from the electromagnetic fields generated by power-lines.
My question is , how can I make the electromagnetic field receiving antenna? Will a simple copper coil work? If so, can the same coil be used as the RF antenna or will that have to...
If Cellular network towers are supposedly divided in cells , like this image , then why do we loose connection even when outdoors and not inside or near any buildings/cars. Also why is it common to see more than 1 cell tower near each other?
So im planning on launching a Satellite to promote the Dogecoin cryptocurrency. One of the main points is printing/painting (Or whatever) the logo on the side of a metal panel. How can I make it so it doesn't melt off or turn white from radiation so quickly?
There is no coax feedline as this is for an electronic transmitter using gunn diodes. I generated the horn measurements from a tool that used to be on this website : http://18.104.22.168/cgi-sys/defaultwebpage.cgi
So I printed this antenna with some conductive filament , however the microwaves seems to be going between the layers of the plastic. I surrounded it with Aluminum and still leaking, what can I do to fix it? Can conductive silver paint work?
