In this paper, a compact frequency reconfigurable circular patch antenna with an arc-shaped slot loaded in the ground layer is proposed for multiband wireless communication applications. By controlling the ON/OFF states of the five PIN diodes mounted on the arc-shaped slot, the effective length of the arc-shaped slot and the effective length of antennas current are changed, and accordingly six ...

Abstract— This paper presents a selective frequency reconfigurable antenna, suitable for cognitive radio applications. Reconfigurability is achieved by inserting PIN diode switches in DMS(defected microstrip structure) ‘T’ slot filter. The proposed antenna is capable of switching between a wide operating band of

Frequency tunability in an antenna enables its use for a range of frequencies [19]. Radio frequency switching normally has been done by using semiconductor devices such PIN diodes or FETsA new frequency-reconfigurable antenna structure, denoted as a pixel slot antenna is proposed in [48]. An investigation of pattern and frequency reconfigurable… A free platform for explaining your research in plain language, and managing how you communicate around it – so you can understand how best to increase its impact.
