I'd like to characterize the gain of a patch antenna I constructed by pointing it at a horn antenna with known gain, then use Friis equation to solve for the unknown gain using the known Tx and Rx power and the distance between the antennas.
Do I use the distance from the patch to the Horn's opening or feed when calculating the distance between antennas?
Thanks!
Tænkte at jeg lige ville spørge herinde - ved I hvorfor hun ikke har været med i programmerne de sidste 2 uger? Ved der evt. har været ferie, men det er bare vildt lang tid??
Synes ikke de har sagt noget...
I have a question regarding friis formula. I was doing some calculations using isotropic antennas and found that @ 915 MHz and 1 cm away with a transmit power of 1 W, the receive power is 6.8 W . This obviously means that the system gains power which is very suspicious. So my question, can a system really gain power?, where does the power come from? My guess is since the distance between the two isn’t large then we treat it like it’s in the near field. Am I right in my hypothesis?
I have literally checked after each and every refresh but he's nowhere to be seen
