ABSTRACT:
A reconfigurable dual mode network (10) in which the maximum voltage amplitudes (a, b, and c, respectively) appearing at three output ports (11, 12, 13), are preselected, reconfigurable, and arbitrary subject only to the constraint that the sum of the squares of any two elements of the set (a, b, c) must be equal to or greater than the square of the third element of this set. The set of complex voltages (A, B, and C, respectively) appearing at the three output ports (11, 12, 13) when an input signal is applied to one of the input ports (1 or 2) is conjugate with the set of output voltages (AA, BB, and CC, respectively) appearing at the three output ports (11, 12, 13) when an input signal is applied to the other input port, which is isolated from the initially selected input port (1 or 2). The lossless and matched network (10), which may be used as a feed network in an antenna (25) system, e.g., as an even/odd mode network, comprises six 3dB quadrature hybrid couplers (31- 36) and six variable phase shifters (41-46). The phase shifters (41-46) impart preselected phase shifts (P1-P6, respectively), specified herein, which are calculated from the desired values of a, b, and c.
