Abstract
The field component diversity antenna and receiver arrangement comprises at least a first pair of parallel spaced, straight, vertical elemental antenna elements disposed substantially parallel to the electric field component of a transmitted signal to receive the transmitted signal in a multipath fading environment where the electric field and magnetic field components are uncorrelated and a 180.degree. hybrid circuit coupled to the first pair of spaced antenna elements to provide a first output signal proportional to the electric field components and a second output signal proportional to the magnetic field component. The spaced elemental antenna elements may be monopole elements or dipole elements. The pair of antenna element may be connected together by a straight conductor to enhance the magnetic field component. The first and second output signals may be combined by known diversity combining arrangement to achieve a diversity advantage.
