Does it help to make antennae shaped like a cube or is it better to have them on one plane(flat)?
Are there methods for calculating the size and ratio of the vanes?
Sorry so layman terms I don't know much about aerials.
(but I do know Shinoloa)
Oh the reason I ask is I want to make a cool and functional aerial for my house.

what do you think a satellite is shaped like? They are all different, so i can't see the relationship.

Antennae have specific shapes, for reasons of maximizing the signal. But there are thousands of different ways of picking a shape, depending on frequency, polarization, and space available.
