Abstract
A transformer system comprises a transformer star winding to be coupled to an antenna system, and a transformer delta winding disposed with said transformer star winding. The transformer star winding includes a set of star elements and the transformer delta winding includes a set of delta elements each being substantially perpendicularly disposed with a corresponding star element from the set of star elements.
