Reconfigurable slot antenna for cognitive radio applications
A compact UWB monopole patch antenna with reconfigurable ...
Compact Reconfigurable Antenna with an Omnidirectional ... A compact reconfigurable antenna with an omnidirectional mode and four directional modes is proposed. The antenna has a main radiator and four parasitic elements printed on a dielectric substrate. By changing the status of diodes soldered on the parasitic elements, the proposed antenna can generate ... Frequency Reconfigurable Microstrip Antenna for Cognitive ... 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 ... T. Aboufoul, A. Alomainy, and C.

A Study of Reconfigurable Multiband Antenna for Wireless ... Frequency Reconfigurable Antenna for Cognitive Radio which is act as a fast switching antenna capable of operating in seven different frequencies in the range of 6.25 to 8.25 GHz[14]. Mohammad M. proposed a Reconfigurable Antenna with Extended U-Slot used as a Switchable Polarization for Wireless Applications. Design of Reconfigurable Band Notches Antenna for Cognitive ... tenna based on a ring slot etched in the patch. In this paper , we propose an antenna for cognitive radio applications. It can be operated as ultra wideband and is reconfigurable in terms of the ability to select a notche d band in the SRR resonant frequency . The rest of the paper is organized as follows. Mohammed Al-Husseini, Karim Y. Kabalan, Ali El-Hajj and ... 2.1. Cognitive radio Cognitive radio (CR) technology is key enabling technology which provides the capability to share the wireless channel with the licensed users in an opportunistic way. CRs are foreseen to be able to provide the high bandwidth to mobile users via heterogeneous wireless architectures and dynamic spectrum access techniques.
