Full-wave modelling of ground-penetrating radars: Antenna mutual coupling phenomena and sub-surface scattering processes

Ground-penetrating radar (GPR) technology finds applications in many areas such as geophysical prospecting, archaeology, civil engineering, environmental engineering, and defence applications as a non-invasive sensing tool [3], [6], [18]. One key component in any GPR system is the receiver/transmitter antenna. Desirable features for GPR antennas...

A Novel Directive, Dispersion-Free UWB Radiator with Superb EM-Characteristics for Multiband/Multifunction Radar Applications

The number of topside shipboard antennas doubled every decade; in 1990s they were close to 200 and have no sight of stop growing (Tavik, 2005). The over-crowded present of such many topside antennas in a limited-space of littoral warfare ship has created/caused many critical, unavoidable problem like antenna blockage, electromagnetic...
