Dipole Antenna Radiation Animation (2 Wavelengths long) (FDTD simulation)

3 in one a trinity

Excellent simulation! Have you ever done Corner Reflector Antenna simulation, using FDTD?

Yagi-Uda antenna has a similar principle, basically by placing several wires in front of the main wire as well as one on the backwards the directivity increases and pattern is modified. But the lengths are not exactly same. Check internet for yagi-uda antennas it can give you some insight. Thanks

Alright thanks. Its hard telling which direction the waves go. I've been thinking on making a dual copper coil antenna. Inner coil + and outer coil - both the same vertical length. I ran a test using neo magnets, and think they might be able to concentrate or add strength to the signal, but would possible cause the coils to resonate from signal transfer..

Thanks for your interest. In principle, you can do that but efficiency and the propagation pattern would be different.

Here's a good question, can we use a Harmonic Antenna that is a multiple of the wavelength and get same result? Say a 2 meter long antenna to pick up or broadcast 1 meter wave?
