All the better for a bit of visual restraint, too, letting the seven slot radiator grille announce this is a Jeep- and proud of it - from 100 paces.

Meanwhile, [F.sub.1] to [F.sub.3] are produced by the slot radiator. The existence of the PIN diode in the slot gives different values for resonant frequencies of [F.sub.1] to [F.sub.3].
Slot coupling from stripline is mostly preferred as it provides wide bandwidth and easy mounting of the active devices below the slot radiator. The main disadvantage of slot radiators is that they radiate on both sides of the array face, and thus there is 3-dB loss and the power radiated down the slot interferes with the devices and may deteriorate the sidelobe level.
introduced a four slot element based on a duplicate two slot radiator in [3], and Simmons used crossed slots in [5].
As shown in Figure 1, the proposed antenna consists of an annular ring slot radiator on the top layer and a hybrid patch coupler on the bottom layer.
The influence of the sphere radius on energy parameters of the slot radiator was studied numerically.
The structure of the proposed antenna, as shown in Figure 1, consists of the slot radiator and a T-shaped feedline.
