HIGH-PERFORMANCE ANTENNA ARRAYS FOR MULTIFUNCTION PHASED ARRAY RADAR (MPAR) APPLICATION
… more signal information without occupying more frequency band. This is because frequency bands are getting crowded in microwave frequencies due to the recent advancements in cellular communications. For example, the Spectrum Efficient National Surveillance Radar Program (SENSR) is started to …

Design and applications of smart antenna systems for wireless networks in the context of the Internet of Things (IOT)
… in the form of thesis by publication. Leaky-Wave Antennas (LWA) consist on a waveguide structure which allows the leakage of part of the power along the structure. For this reason, the radiation of the antenna is produced by the leakage of power. In order to produce coherent radiation, it is …
