UWB Sensing Antenna, Reconfigurable Transceiver and Reconfigurable Antenna Based Cognitive Radio Test Bed

Published: 01 October 2017 Publication History

Abstract

For the effective use of available frequency bandwidth, cognitive radio technology is evolving in the last few years. In this, spectrum is shared between primary and secondary users. Secondary users also called as unlicensed users, makes use of part of spectrum which is not used by primary or licensed users. Hence secondary user systems must be capable of sensing the spectrum and should be able to reconfigure to transmit at different frequencies. For this it must consists of spectrum sensing circuit and a reconfigurable transceiver consisting of reconfigurable antenna. This paper discuss the single module of reconfigurable transceiver which dynamically allocates two different frequencies 2.4 and 3.1 GHz for transmission. Ultra-wideband patch antenna, spectrum sensing algorithm and reconfigurable patch antenna are also discussed. The module can be modified to transmit at more frequencies in the range 2.4---9 GHz by having reconfigurable devices such as LNAs, power amplifiers, local oscillators, mixers, etc.
