My experiments with microwave antennas from 1-24 GHz (mostly Vivaldi)


My best variant "Vivaldi V5" for the 13/9/6/3cm ham radio bands

For the main bands it is obviously a λ/2 antenna with quite nice and flat SWR over a broad range.
As you can see it is also resonant on 23cm (presumably λ/4 only), but I didn't do further investigations there.
I have some antennas left, if you are interested pls. contact me.

Coming soon

  • a compact 9cm transverter (ZF: 144MHz/<=30dBm, RF: 3400MHz/>=13dBm, LO: 3256MHz/~13dBm)
