Abstract :
Here we describe our work designing multiple flare-angle horns, optimised using a genetic algorithm. Several horns designs will be described and experimentally measured beam patterns for horns at 230 GHz will be presented. In addition, we will present new, wide bandwidth horns offering good performance over a ~30% bandwidth.
