TLDR
A wide variety of antennas have been designed or are currently under study for the millimeter wave region as discussed by the authors, and an overview over these antennas is presented in this paper. But, as mentioned before, the antennas of conventional configuration and antennas based on new design approaches are distinguished, and antennas with significant features that are peculiar to the mm-wave band can be distinguished.Abstract:
A wide variety of antennas has been designed or is currently under study for the millimeter wave region. An overview over these antennas is presented. Two classes of antennas are distinguished, i.e., antennas of conventional configuration and antennas based on new design approaches. The former class consists of radiating structures, such as reflector, lens and horn antennas, whose characteristics are well established. The latter class is comprised of antennas with significant features that are peculiar to the mm-wave band and includes radiating structures such as microstrip mm-wave antennas, dielectric antennas and integrated antennas.read more
