With rapidly increasing demand for bandwidth, and the recent advances in nano-metric Si-based integrated circuit technologies, millimeter-wave (mmW) systems are finding numerous commercial applications, which, unlike military and scientific usages, are extremely cost sensitive. A wide range of applications at mmW frequencies can be found in such area as wireless communications network (60 GHz), automotive...
A compact, low cost and high radiation efficiency antenna structure, planar waveguide, substrate integrated waveguide (SIW), dielectric resonator antennas (DRA) is presented in this paper. Since SIW is a high Q- waveguide and DRA is a low loss radiator, then SIW-DRA forms an excellent antenna system with high radiation efficiency at millimeter-waveband, where the conductor loss dominates. The impact...
