Reconfigurable Trident Antenna for Cognitive Radio Applications

EasyChair Preprint 9292

Abstract

This article presents the design and implementation of an 30x30x1.6 mm³ reconfigurable antenna with multiple operating states. Four PIN diodes as S₁,S₂,S₃ and S₄ are used to reconfigure the transmission frequency to achieve ultra wide band (UWB) of frequency range 3.6GHz-13GHz and multiple narrow band (NB) frequencies are achieved at different conditions of switching. This switching makes the antenna appropriate for cognitive radio applications by preventing interference from the primary user into the secondary user. The proposed antenna consists of a trident shaped UWB antenna compact single port with defected ground structure (DGS) of complimentary ring resonators (CRR). The simulated results indicate that the antenna has good impedance as well as radiation properties.This article presents the design and implementation of an 30x30x1.6 mm³ reconfigurable antenna with multiple operating states.
