“…In addition, it also has a measured high gain in the range of 11.5 -12 dBi spanning the frequency range of 57-64 GHz. The paper [16] presented the performance of a wideband substrate integrated waveguide (SIW) based slot antenna at the D band (110 -170 GHz). The emergence of a wideband response can be associated with the convergence of six closely spaced resonance frequencies.…”

Researchers are keen to continue developing and investigating millimeter wave spectrum bands because these bands potentially provide broadband bandwidth for extremely high data transfer rates. This paper presents a comprehensive review of the recent millimeter wave antenna development, especially for 30-40 GHz, 60 GHz, and 140 GHz, with their characteristics, limitations, and challenges. Several previous millimeter wave antennas are introduced, including their broadband bandwidth, gain, feeding technique, substrate, and beamwidth. Based on their measured performances show that the millimeter wave antenna has great potential to support realizing the extremely high transfer data rate in wireless communication systems.

“…SOLT calibration was performed up to the connecting WGs before measuring the DUT. A pair of circular fixtures was used to hold the To address the shift in the measurements, we modeled the frequency-dependent behavior of the dielectric constant using the Debye model using HFSS, as in one of the earlier studies [14], and the comparison of the results is plotted in Fig. 16.…”

In this work, a design of a transition from a standard D-band waveguide to substrate integrated waveguide (SIW) technology is presented for 6G applications. The waveguide is connected to an SIW by carving a slot at the bottom metal of the printed circuit board (PCB). A pair of vias is added to shift the inband null to a higher frequency, whereas a parasitic patch is used to improve impedance matching. A prototype of a back-to-back SIW transition is fabricated and measured using D-band VNA extenders. The measurement shows a −10 dB impedance bandwidth of 26.5 GHz (135–161.5 GHz) and a 3 dB bandwidth of 28 GHz (133.8–161.8 GHz). The transition can be integrated with a D-band antenna for 6G applications.

“…To solve the losses generated by the path at millimeter wave frequencies, it is often necessary to design antennas with high directivity. In recent years, the way to improve the antenna gain is mostly through the array structure to achieve higher directivity, such as [3,[10][11][12][13][14] are through the array structure to improve the radiation directivity. In [10], a slot array using corporate-feed is introduced to achieve a homogeneous feeding network through the slot waveguide, and metal pins are added to the radiation slot to increase the bandwidth.…”

This paper proposes a design of a multilayer controlled beam horn antenna for the D-band. The multilayer design can achieve easy to control, low cost, and compact structure. The designed structure achieves the effect of a conventional horn antenna by stacking multiple layers and realizes the effect of beam switching by modifying the multi-layer plate structure. The widest bandwidth can be obtained when stacking 4 layers of boards, covering 24.7% (110-141GHz) of the bandwidth with a simulation gain of approximately 13.5dBi. By replacing the third plate structure, beam switching of ±30 degrees can be achieved, and the gain after beam switching can also reach 11.5 dBi. Horn, antenna, D-band, beam switching, multi-layer.
