“…It is interesting to note that in general ZL # Z;. That is, the input impedance of patch 1 with patch 2 open-circuited is not the same as the input impedance of patch 2 with patch 1 open-circuited. This occurs because each probe feed is in a different location with respect to the other patch.…”

A full‐wave solution for the mutual coupling between circular microstrip patches fed by idealized vertical probe feeds is presented. The grounded slab Green's function is used together with the moment method to determine the current distribution on each patch. From this, the patch port impedance matrix and, hence, the mutual coupling can be determined. Measured data that validate the theory are presented.

“…(5) is calculated, the mutual coupling coefficient S,, can be readily obtained from In Eq. (13), the characteristic impedance Zo of the feeding coax is chosen to be 50 R, and the self-impedance Z,, is assumed to be equal to the input impedance, adjusted to be 50 R, of an isolated antenna, following the assumption that the mutual coupling does not disturb the interior field distribution under the patch [3].…”

f i e mutual coupling between cylindrical-circular microstrip antennas is studied by applying the cauity-model analysis and the reaction theorem. fipressions of the mutual coupling coejjicients for the E-plane and H-plane coupling cases are presented. Theoretical results are calculated, and the curuature effects on the mutual coupling are discussed. 0 1995 Microwave and Optical Technology Letters, l O / l , 39-41 0 1995 John Wiley & Sons, Inc.

“…The mutual coupling between rectangular antennas has been computed using transmission line techniques [2]. In [3], the authors have computed mutual coupling between circular microstrip antennas using cavity model and reaction theorem. An expression is presented in [3] with the constraint that certain coefficients are to be deduced by numerical computation.…”

“…In [3], the authors have computed mutual coupling between circular microstrip antennas using cavity model and reaction theorem. An expression is presented in [3] with the constraint that certain coefficients are to be deduced by numerical computation. Some other mutual coupling estimation techniques related to circular microstrip antennas are full-wave solutions [4] and generalized transmission line techniques [5].…”
