Abstract
Disclosed herein are various exemplary embodiments of multi-band, wide-band antennas. In exemplary embodiments, the antenna generally includes an upper portion and a lower portion. The upper portion includes two or more upper radiating elements and one or more slots disposed between the two or more upper radiating elements. The lower portion includes three or more lower radiating elements and one or more slots disposed between the three or more lower radiating elements. A gap is between the upper and lower portions such that the upper radiating elements are separated and spaced apart from the lower radiating elements. The antenna may be configured such that 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.
