In , the frequency-reconfigurable aperture coupled antenna
is achieved by controlling the switch at the slot on the ground plane.
Caption: Figure 7: Layout of the T-shaped probe coupled antenna
To obtain wideband circular polarization characteristics, a dual-slot coupled antenna
excited by an H-shaped slot fed by a T-shaped microstrip was designed as the radiating element of a rectenna array.
Equations (2) and (4) provide a complete solution to the problem of coupled antenna
arrays, based on the sinusoidal approximation for the currents.

This is an interesting result which is totally different from the microstrip fed aperture coupled antenna
where the microstrip feed must be in the centre of the slot to achieve best coupling .
The two FETs are connected in a symmetrical arrangement to the coupled antenna
, and thus the circuit may be analyzed separately in its even and odd modes of operation.
It is also shown that the passive and lossless decoupling and matching networks can be used to transform the coupled antenna
ports into independent and matched ports.
The envelope correlation coefficient presents an important factor for the comparison of MIMO capabilities of coupled antennas
In , a broadband decoupling network for two tightly coupled antennas
was proposed using inserting a second-order coupled resonator filter network between the coupled antennas
