 |
|
I am working on a project that varies antenna geometry to see how different parameters change. In general, I am wondering what the effect of different geometric arrangements in antennas has on resonance at the above-800 MHz range. Is there a formula that is applicable in this case? In what way does the shape change affect the resonant frequency? Any guidance would be appreciated. I don't quite understand what's going on.  |

As for above 800 MHz, it doesn't matter at all what frequency you are talking about. The rules of antennas state that an antenna that is 4" long will behave at 800 MHz exactly as an 8" long antenna will at 400 MHz. So you can scale your results to any frequency.
As for geometry affecting the resonance, there is no simple answer. I would suggest spending some time understanding the basic antenna types (patch antenna, dipole antenna, slot antenna, etc) to get an understanding or feel for antennas:
