Millimeter-Wave Rectangular Dielectric Resonator Antenna Array With Enlarged DRA Dimensions, Wideband Capability, and High-Gain Performance

Wideband Circular Polarized Dielectric Resonator Antenna Array for Millimeter-Wave Applications

“…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 differential‐fed dual‐polarized antenna with gain enhancement using hollow dielectric patch resonator

“…[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. Among them, the most common approach is to integrate the DR with a horn.…”

“…Among them, the most common approach is to integrate the DR with a horn. [8][9][10] Another approach uses the multilayer stacked anisotropic resonator to increase the radiation from the sidewalls of the DR. [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.…”
