Conference Proceeding
Mehdawi, M., Riley, N., Ammar, M., & Zolfaghari, M. (2012). Comparing historical and current spectrum occupancy measurements in the context of cognitive radio. In 20th Telecommunications forum TELFOR 2012, 623-626. doi:10.1109/telfor.2012.6419287

Cognitive radio (CR) technology promises to be one possible solution to solve the problem of lack of frequency spectrum, by allowing access of unlicensed users in licensed bands, based on an opportunistic approach and without interfering with the lic...

Reduced-size circularly polarised square microstrip antenna for 2.45 GHz RFID applications (2012)
Journal Article
Nguyen, D., Paulson, K., & Riley, N. (2012). Reduced-size circularly polarised square microstrip antenna for 2.45 GHz RFID applications. IET Microwaves Antennas and Propagation, 6(1), 94-99. doi:10.1049/iet-map.2011.0269

This study proposes a new design of circular polarised (CP), microstrip (patch) antenna using a set of slits and slots to effectively reduce the area of patch by 67% compared with the conventional, corner truncated, circular polarised square patch. T... Read More about Reduced-size circularly polarised square microstrip antenna for 2.45 GHz RFID applications.
