The replacement and elimination of duplexers in a tightly coupled dipole phased array starts with transmit and receive functions physically separated and having different antenna port feeds. The simple coupling network used with tightly coupled dipole arrays is replaced by a state switch which alternates between a coupling state and a dipole feed connection state. The basic method can be applied to antenna apertures of various kinds, including both linear and dual polarized versions. The ability to locate state switches at various nodes in tightly coupled dipole phased arrays permits flexibility in antenna design and eliminates bulky and lossy components, simplifies the design requirements and allows independent optimization of the components.
A method for elimination of duplexers in transmit/receive phased array antennas, comprising the steps of:
A tightly coupled phased array comprising:
A tightly coupled dipole array coupling a first set of dipoles aligned in one direction and a second set of dipoles aligned in an orthogonal direction to form an orthogonal matrix of dipoles, each of said dipoles having a feedpoint and a pair of dipole element ends;
