This paper shows a frequency reconfigurable SIW F-slot suitable for some applications. Configurability is accomplished by embeddings PIN diode switches in the 'F' slot. The proposed antenna equipped exchanging between working band of 3.172 GHz to 3.606 four different narrow bands and it underpins cognitive system LTE2300, WiMAX WLAN. For each case reflection coefficient ascertained, keeps up less than -10 dB all through resonating instances switching. electromagnetic energy kept inside cavity because frame metallic vias. In diodes exchanging, it's uncovered decent effectiveness efficiency gain.
