Frequency Reconfigurable Antennas Design for Cognitive Radio ...

Frequency Reconfigurable Microstrip Patch Antenna for ... The antenna structure has three switches which are placed in the lower slot of antenna in order to produce six different frequency bands. The antenna can be used for cognitive radio systems where sensing and reconfigurability are key metrics of working. It can also be used for WiMAX applications with necessary modifications. Design of Reconfigurable Meander-line MIMO Antenna for ... meander-line planar MIMO antenna for CR (Cognitive Radio) applications. The reconfigurable antenna which is capable of modifying dynamically its frequency and radiation properties in a controlled manner. Meander-line is a type of printed antenna that can achieve miniaturization in size by embedding a wire structure onto a dielectric substrate. A Compact Integrated UWB/Reconfigurable Microstrip Antenna ... This paper presents a compact sensing/communicating antenna configuration for interweave cognitive radio (CR) systems. The sensing antenna is an ultra-wide band (UWB) planar monopole antenna, while the communicating antenna is a reconfigurable microstrip antenna etched on the backside of the UWB antenna radiating patch.

Compact Reconfigurable UWB Slot Antenna for Cognitive Radio Applications

Abstract. A compact and reconfigurable band notch UWB antenna for cognitive radio application has been proposed in this paper. The proposed UWB antenna has dual notch band in WI-max and WLAN and has reconfigurable property in terms of band notching for a single notch band in Wi-Max.
