“…The antenna that was made from individual parts is then assembled to produce the final array. This was done so the performance of the individual parts could be verified [17]. A reference design was also assembled for comparison, with the three delay line sections all replaced with straight waveguide sections, to measure the beam squint of a conventional array.…”

Series feeds are commonly used in antenna arrays because of their compact size and low loss compared to corporate feeds but typically feature beam squint over wide bandwidths. This work proposes a series-fed waveguide horn array with reduced beam squint by introducing synthesized time delay sections between the horns and the feed line. The array, implemented in a WR42 waveguide, achieves 1.53° beam squint over a 4 GHz operating band, compared to 10.52° for a reference design without time delay compensation.

“…The standard array is referred to as the uncompensated array in this work while the compensated array uses time delay sections to compensate for the beam squint. The manufacturing process is discussed in more detail elsewhere [17,18].…”

“…By carefully designing the dielectric structures, the antenna can achieve desired radiation characteristics, such as beam steering and shaping [36][37][38]. The simplified design and manufacturing process of dielectric waveguide antennas can lead to lower production costs process [39][40][41], which is particularly significant for millimeter-range antennas. Overall, the advantages of dielectric waveguide antennas make them a promising choice for various applications, including wireless communication systems, radar systems, and satellite communication [42,43].…”

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.
