A meander line loaded antenna (200) provides a wide instantaneous bandwidth with a first planar conductor (204) extending orthogonally from a ground plane (201), a second planar conductor (202) substantially parallel to the ground plane (201) and separated from the first planar conductor (204) by a gap (206), a meander line interconnecting the first and second planar conductors across the gap (206), and third conductor (212) connecting the second planar conductor to ground. A fourth conductor (210) provides enhanced capacitance between the first and second planar conductors. The antenna may be arranged in opposed pairs, and also as two orthogonally opposed pairs for enabling circular polarization. Applications include communications systems requiring wide instantaneous bandwidth and multimode capability. |
