Abstract
A dual linear polarized dipole antenna (and arrays of such antennas) having high isolation between ports. The antenna may include a pair of crossed (collocated) bent (angled) dipole antenna elements which are excited by a unique dual-polarized feeding structure. The antenna elements may be printed. Stripline feeding along with substantially symmetrical and substantially identical radiative (e.g., 'radiating') elements results in high level of port isolation. Sub-ground planes may be positioned about the stripline on both sides of a balun block to limit or reduce parasitic stripline radiation, thereby improving polarization purity. Polarization purity may be additionally reinforced by a principal ground plane which isolates the radiative elements from the baluns. The antennas and antenna arrays may be used, for example, for weather observation and air surveillance.
