bent wire 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.

Hi,

I am pretty new to antenna analysis. I'm trying to figure out what the radiation pattern of a dipole bent in half 90 degrees (in the shape of an L) looks like. Can I calculate the pattern mathematically or should I just use simulation software?
Also, how would I calculate the input impedance of such an antenna?

Thanks.

Greetings Guest:

Use of an EM simulator appears to be in order to get a meaningful field pattern and input impedance. My cheap FM stereo antenna works great when I bend it in the middle (approximately) to get the best pickup in my somewhat rural location.

A couple free EM programs are available on the "Antenna, Electromagnetics & Transmission Line Simulators" area on the software page.


Let us know what you come up with.
