Carberry, "A technique to simulate the self and mutual impedance
of an array," IEEE Trans.
The active element patterns have a specific relationship with mutual impedance
matrices in array antennas.
Away from having naturally decoupled antennas, a decoupling [lambda]/4 or 3[lambda]/4 transmission line connected between matched, coupled two antennas at specific distances from the antennas input ports, where the equivalent mutual impedance
observed is pure imaginary, is a solution proposed in .
The same figure also plots the frequency dependence of the 16 eigenvalues of the mutual impedance
matrix and -[Z.
II] of the body; the second is similar modulation, obtained by changing the mutual impedance
resistivity method (Keller and Frishknecht, 1966) and measurements of mutual impedance
of loop antennas working at the high frequency.
Such geometrical and material considerations in realizing closely proximal antennas with minimum mutual impedance
consideration need a careful design strategy.
m] the matching impedance of each antenna, and Z the mutual impedance
Gupta studied the effect of mutual coupling on the performance of adaptive arrays and adopted the conventional mutual impedance
method (CMIM) to reduce the effect of mutual coupling .
That is called the driving point impedance, which consists of self-impedance, mutual impedance
and the ratio of their current distributions.
The measurement of the mutual impedance
of loop antennas situated near a conducting half space is a well-known technique used in geophysical investigations.
