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.
