Abstract:
1. A multi-band, wide-band antenna comprising: an upper portion including two or more upper radiating elements and one or more slots disposed between the two or more upper radiating elements; a lower portion including two or more lower radiating elements and one or more slots disposed between the two or more lower radiating elements; a gap having two open ends between the upper and lower portions such that the upper radiating elements are separated and spaced apart from the lower radiating elements, the gap including a plurality of rectangular portions defining a stepped configuration, wherein the plurality of rectangular portions of the gap comprises a first rectangular portion and a second rectangular portion that is narrower than the first rectangular portion, the second rectangular portion extending from an edge of the antenna towards an opposite edge of the antenna to intersect with the first rectangular portion; whereby coupling of the gap and the upper and lower radiating elements enable multi-band, wide-band operation of the antenna within at least a first frequency range and a second frequency range, with the upper radiating elements operable as a radiating portion of the antenna, the lower radiating elements operable as a ground portion, and the gap operable for impedance matching.
