ABSTRACT:
There is disclosed herein a multi-turn antenna which comprises an electrically conducting surface. This surface consists of an even plurality of symmetric pairs of hollow, substantially isosceles triangular loops. Each pair of loops is electrically connected to its adjacent pair. Each pair comprises an electromagnetic wave guide. Each symmetric pair is disposed parallel to its adjacent loop pair. All loop pairs are disposed perpendicularly to the direction of wave propagation, as defined by a primary broadcast source.
