Cracking is a common distress type in asphalt pavements causing degradation of bearing capacity of subsurface layers and putting user's safety on stakes. Therefore, cracks must be detected and cured. Conventional, destructive methods for crack detection are usually time-consuming and expensive. Ground Penetration Radar (GPR) has been successfully used since decades as a non-destructive tool for pavement...
A low profile antenna consisting of a wideband monopole over an artificial magnetic conductor (AMC) is presented in this paper. The AMC is a dual band structure, manufactured on 3.2mm thick FR-4 substrate with the reflection phase in the 2.0 GHz and 5.8 GHz ranges. A wideband printed circular disc monopole antenna uses this dual band AMC as a ground plane resulting in a low profile multiband antenna...
