Abstract :
We are designing a triple band feedhorn structure that is intended to become a future replacement of existing LNB feedhorns on satellite dish assemblies. Here we show work on the first stage of the design; the band 2 and 3 structure which must have a return loss performance of - 20dB or better. We also present results of a model to generate circularly polarised waves for testing in the laboratory.
