Cognitive Radio Transceivers: RF, Spectrum Sensing, and Learning Algorithms Review
International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 A cognitive transceiver is required to opportunistically use vacant spectrum resources licensed to primary users. Thus, it relies on a complete adaptive behavior composed of: reconfigurable radio frequency (RF) parts, enhanced spectrum sensing algorithms, and sophisticated machine learning techniques.

Design of a Two‐Element Antenna Array Using Substrate Integrated Waveguide Technique
International Journal of Microwave Science and Technology, Volume 2011, Issue 1, 2011., 2011 The design of a two‐element antenna array using the substrate integrated waveguide (SIW) technique and operating at 10 GHz is presented. The proposed antenna array consists of two SIW phase shifter sections with two SIW slot antennas. The phase shifting is achieved by changing the position of two inductive posts inserted inside each element of the ...
