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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
