“…As compared with the DRA working in the microwave band, the size decreases extremely in mm-wave frequency which affects their practical realization. However, various shapes have been explored in the recent studies of mm-wave DRA [ 5 , 6 , 7 , 8 ].…”

A novel circular polarized dielectric antenna array (DRA) for millimeter-wave applications at 30 GHz is presented in this paper. The unit element array is a flower-shaped DRA fed with a cross slot. To obtain circular polarization, a sequential network combined with the cross slots is used to feed the 2×2 array. The prototype of the proposed antenna array is fabricated and measured to obtain a wide resonance bandwidth from 27 GHz to 38 GHz frequency band. Furthermore, this left-hand polarized antenna array has achieved a peak gain of 9.5 dBi with 3-dB axial ratio at 30 GHz. The proposed DRA array with wideband resonance and gain bandwidth has the potential to be used for millimeter-wave wireless communications at the 30 GHz band.

A high-gain millimeter-wave patch array antenna is presented for unmanned aerial vehicles (UAVs). For the large-scale patch array antenna, microstrip lines and higher-mode surface wave radiations contribute enormously to the antenna loss, especially at the millimeter-wave band. Here, the element of a large patch array antenna is implemented with a substrate integrated waveguide (SIW) cavity-backed patch fed by the aperture-coupled feeding (ACF) structure. However, in this case, a large coupling aperture is used to create strongly bound waves, which maximizes the coupling level between the patch and the feedline. This approach helps to improve antenna gain, but at the same time leads to a significant level of back radiation due to the microstrip feedline and unwanted surface-wave radiation, especially for the large patch arrays. Using the SIW cavity-backed patch and stripline feedline of the ACF in the element design, therefore, provides a solution to this problem. Thus, a full-corporate feed 32 × 32 array antenna achieves realized gain of 30.71–32.8 dBi with radiation efficiency above 52% within the operational band of 25.43–26.91 GHz. The fabricated antenna also retains being lightweight, which is desirable for UAVs, because it has no metal plate at the backside to support the antenna.

“…To meet the development requirement of high gain, the gain enhancement approaches of the DR antenna have been widely studied, 8‐16 which generally fall into three categories. Among them, the most common approach is to integrate the DR with a horn 8‐10 . Another approach uses the multilayer stacked anisotropic resonator to increase the radiation from the sidewalls of the DR 11‐13 .…”

“…[3][4][5][6][7] Nevertheless, the conventional DR antenna with uniform medium radiates through both the top wall and sidewalls, which has relatively low gain compared to the MP antenna. 3 To meet the development requirement of high gain, the gain enhancement approaches of the DR antenna have been widely studied, [8][9][10][11][12][13][14][15][16] which generally fall into three categories.

[11][12][13] Furthermore, benefiting from multimode nature, designing the DR antenna to operate at the higher-order modes is a convenient and effective way to enhance the gain. [14][15][16] However, the majority of the resultant antennas are complicated in structure or high in profile, which will be a major obstacle to the DR antenna in certain spacelimited applications.…”

A differential-fed dual-polarized dielectric patch (DP) antenna with high gain, wide bandwidth, and high isolation is investigated in this article. Based on the analysis of the anisotropic property of the DP antenna, further exploration of gain enhancement is carried out. The introduction of the square air hole in the substrate to obtain a hollow DP resonator is a crucial technique. It not only increases the electromagnetic radiation from the sidewalls of the DP resonator to further improve the gain to 8.9 dBi, but also shifts the dominant TM 101 mode upward to get close to the higher-order TM 121 mode to achieve bandwidth expansion of 19.4%. By using the differential-fed scheme to excite the TM 101 mode, TM 121 mode and their degenerate modes, dual-polarization operation and high isolation level can be obtained simultaneously.
