| Summary: | 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 is equipped for exchanging
between working band of 3.172 GHz to 3.606 GHz in four different narrow
bands and it underpins the cognitive system for LTE2300, WiMAX and
WLAN. For each case reflection coefficient is ascertained, it keeps up less
than -10 dB all through the resonating frequency in all instances of diode
switching. The electromagnetic energy is kept inside the cavity because of
the frame of a metallic vias. In all instances of diodes exchanging, it's
uncovered a decent effectiveness of efficiency and gain.
