Silicon image guide (SIG) coupled resonators antenna for millimeter-wave/THz applications

Recently dielectric antennas have gained a huge interest in millimeter-wave (mmWave) and THz range of frequencies for a wide range of applications such as wireless communication, imaging, and radioastronomy. The most common type of dielectric antenna is the tapered antenna, which is inherently long and radiates in the endfire direction. To realize a down-sized antenna for radiating in a tilted angle, the idea of dielectric resonator in the configuration of dielectric waveguide antennas can be utilized.
