Figure 5 Normalized main beam gain as a function of parasitic element spacing d

sive option. The analysis presented here is for a horizontally polarized feed, suitable for terrestrial communications operating in most common fading conditions. The limitation of this type of approach is the degradation in the radiation pattern for large offsets in feed position, leading to a maximum usable angular skew. Parasitic elements introduced into feed systems also lead to higher levels of feed blockage due to the increased physical size of the feed.
