The center of the SIDR is the same as the center of the coupling slot
, and the SIDRA element operates at the dominant [TE.sup.x.sub.111] mode for radiation.
The ground plane consists of an I-shape coupling slot
and is loaded under the radiating patch element.
In , an array of dual linearly polarized rectennas fed by a coupling slot
was studied to wirelessly supply actuators.
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.
In order to calculate the length of the coupling slot
, a graph is presented in Figure 7 which shows different values of [X.sub.1] and [X.sub.2] as a function of slot length for different slot widths.
The difference of the coupling slot
results in a significant improvement in the impedance and axial ratio bandwidths by 65% and 190%, respectively, when compared to the cross slot design.
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 lower layer is the feed path of the [DELTA] port and feeds the power dividers through the coupling slot
. In addition, the position of the pin in the waveguide of the [SIGMA] port can be adjusted for the best impedance matching.
