Abstract
This invention discloses an antenna element (12) or an array of antenna elements (52) for use in multifunctional systems which exhibits wide bandwidth, small size, polarization diversity and conformality. In one preferred embodiment, an array of circular conductive patches (56,58) are formed on a dielectric substrate (54) in which adjacent patches are formed on opposite sides of the substrate (54). Each of the opposite conducting patches (56,58) are configured to form a dual flared slotline such that an electric field created between the two conductive patches (56,58) will exhibit a wide range of impedance matching to free space. By exciting the conductive patches (56,58), radiating electromagnetic waves having a polarization with respect to the orientation of the slotlines is produced. By this, a single array of antenna elements (52) can be used in a multifunctional system.
