“…The use of dielectric materials allows for miniaturization and integration of the antenna elements, making them suitable for applications where space is limited [29,30]. It also exhibits low cross-polarization levels compared to waveguideslot arrays [31][32][33], it means that the antenna can effectively transmit or receive signals with minimal interference from undesired polarizations [34,35]. By carefully designing the dielectric structures, the antenna can achieve desired radiation characteristics, such as beam steering and shaping [36][37][38].…”

This paper addresses the issue of constructing millimeter band antennas using dielectric waveguide structures. A new type of linear antenna, incorporating metal pins on the side walls of the grooved dielectric waveguide, is proposed for generating polarization perpendicular to the waveguide axis. However, these antennas suffer from the drawback of cross-polarized radiation in directions close to the waveguide axis. To overcome this limitation, a modified antenna design with transverse polarization is introduced, featuring a closed groove waveguide with a longitudinal slot in the top of wall. The paper provides a comparison between two types of dielectric waveguide antennas. First, waveguide antenna with grooves in the dielectric which resulting longitudinal polarization, and second, waveguide antenna with quarter-wavelength pins which resulting transverse polarization. Electrodynamic modeling data is provided to demonstrate the effectiveness of the proposed antennas for satellite, 5G antenna, and radar applications. Finally, antenna of quarter-wavelength pins is proposed with frequency of 39GHz, gain of 19.8dBi, width of radiation pattern of 3.2$^{\circ}$ and side lobe level (SLL) of -13.3dB has been achieved.
