Frequency Reconfigurable Antennas Design for Cognitive ... This paper proposes frequency reconfigurable antennas using genetic algorithm, suitable for cognitive radio applications. The optimization is applied to find the slot shape and the switches locations in the ground plane of monopole antennas for adjustment of the bandwidth. A Survey on UWB and Reconfigurable Antennas for Cognitive ... Abstract. In this paper, a survey on ultrawide band and reconfigurable antennas for cognitive radio application is presented. Cognitive radio is an intelligent wireless communication system that is aware of its surrounding environment (i.e., outside world), and uses the methodology of understanding-by-building to learn from the environment and adapt its internal states to statistical ... Reconfigurable Multi Band Notches Antenna for Cognitive ... In this paper, a reconfigurable multi band notches antenna, for cognitive radio applications, is proposed. The antenna can be operated as ultra wideband, and is reconfigurable in terms of the ability to select one or two notches band in the SRR resonant frequency.

A compact reconfigurable and notched ultra-wideband (UWB) tapered slot antenna (TSA) is presented. The antenna reconfiguration operation principle relies on 2 mechanisms: in the first mechanism a resonator parasitic microstrip line electrically coupled to the TSA is used to notch the TSA at a specific frequency and the second mechanism relies on changing the input impedance matching of the ...

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 3.0 GHz – 10 GHz and six different narrow band operating from 5 GHz to 10 GHz. A Reconfigurable Triple-Notch-Band Antenna Integrated with ...

PDF | A new planar reconfigurable wideband slot antenna is proposed for cognitive radio (CR) applications in this paper. The wideband function is obtained by inserting a meander ε-shaped slot in ...

Compact Reconfigurable UWB Slot Antenna for Cognitive ... Abstract: A very compact reconfigurable ultrawideband (UWB) stepped-slot antenna for cognitive radio (CR) applications is presented in this letter. The proposed antenna operates in two modes: UWB mode for sensing application and communicating mode for different narrow/wideband communication applications.
