ABSTRACT:
An antenna having a frequency separator of the type comprising plural lattice structures of a periodic conductive pattern. Each lattice structure exhibits an inherent resonance frequency and an inductance-capacitance effect at frequencies below the inherent resonance frequency. The periodic conductive patterns are selected so that each of the lattice structures exhibits substantially the same inherent resonance frequency, and when placed at selected intervals, the plurality of lattice structures exhibit interactive resonance at frequencies below the inherent resonance frequencies. Each lattice also exhibits substantially equal inductance and capacitance with respect to obliquely incident electromagnetic waves in the TE and TM modes.
