TLDR
In this article, a dual band microstrip antenna including a slotted microstrip radiating pllel to and spaced from a ground plane with dielectric material therebetween, the slotted nano-strip having a first resonance corresponding to the dominant radiation mode that would occur in an unslotted micro strip and a second resonance created by the slot.Abstract:
A dual band microstrip antenna including a slotted microstrip radiating pllel to and spaced from a ground plane with dielectric material therebetween, the slotted microstrip radiating and having a first resonance corresponding to the dominant radiation mode that would occur in an unslotted microstrip and a second resonance created by the slot. The polarizations of the two resonances are perpendicular to each other with the slot resonance being polarized along the centerline of the slot.read more
