In , the frequency-reconfigurable aperture coupled antenna
is achieved by controlling the switch at the slot on the ground plane.
To detect obrusnE'ch layers are required Horn Antenna and Ground Coupled Antenna
, diagnostic core groud Coupled Antenna
Equations (2) and (4) provide a complete solution to the problem of coupled antenna
arrays, based on the sinusoidal approximation for the currents.
In addition, the passive and lossless decoupling and matching networks using reactive lumped elements can be used to transform the coupled antenna
ports into isolated and matched ports, for example, the design of decoupling network for two-element arrays in [18, 19].
Detailed analysis of equivalent circuit modeling of capacitive coupled antenna
may be found in .
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 .
In the odd mode at the frequency of oscillation, the coupled antenna
appears as a transmission line periodically loaded with sections of low impedance, thus presenting a large return loss to the FETs.
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
It has been found that E-plane coupled antennas
suffer from stronger mutual coupling than H-plane coupled antennas

and noisy amplifiers," Progress In Electromagnetics Research C, Vol.
Another analytical procedure in [8,9] using factorization techniques to get the required scattering matrix of the decoupling network suggests using 180[degrees]-Hybrid to isolate two coupled antennas
Two transmission lines are individually connected to input ports of two strongly coupled antennas
in the decoupling network.
