The lower layer is the feed path of the [DELTA] port and feeds the power dividers through the coupling slot
The ground plane, which includes a coupling slot
, is located at the mid layer.
The discrepancy between the measured results and the simulated results may be caused by the introduction of the coupling slot
on the ground plane.
The improvement in bandwidth is due to the flexibility offered by the slot length and coupling slot
The resonator spacing and coupling slot
at the high magnetic field point of the helical structure facilitates inter-resonator coupling.
The array was configured in a nonuniformly spaced traveling-wave array form, in which the radiating amplitude and phase of each element can be controlled by tuning the length of the coupling slot
and the distances between the elements, respectively.
In case of electromagnetic coupling, switchable patch antennas have been realized by placing the PIN diode switches in the feeding network or the coupling slot

The proposed solution involves the use of an asymmetric stripline only in the vicinity of the micro-strip-to-stripline coupling slot
Two kinds of dual-mode cavity resonators are coupled through arcshaped coupling slot
