| | loss resistance of a small loop antenna - RF Cafe Forums |
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

What is the formula to calculate the loss resistance of a small loop antenna having a square shape?

Location: London UK | The formula I have is for circular loops, but I understand the important quantity is the perimeter, not the shape.
For a copper wire antenna
Loss Resistance is = 0.000996*SQRT(F)*perimeter/diameter of wire
all dimensions in meters and MHz

Wrong again. The perimeter and radius should be in feet and inches respectively in the previous posting

Posts: 8 | And now what is the inductance of a square small loop made of copper wire?

See the book Inductance Calculations by Grover - available through Amazon (surprise!).
Good Luck!
