Dual-Band SIW Cavity-Backed Slot Array Using TM₀₂₀ and TM₁₂₀ Modes for 5G Applications

Characterization and Design of Wideband Penta- and Hepta-Resonance SIW Elliptical Cavity-Backed Slot Antennas

“…In [18], a cavity mode TE 210 and an additional patch mode are excited to achieve a bandwidth of 15%, which, in fact, is still narrow. Moreover, the published SIW CBSAs are mainly implemented with the ordinary rectangular cavities [4]- [19], circular cavities [20][21][22][23][24][25], triangle cavity [26], and hexagonal cavity [27]. To this end, novel broadband antenna topologies need to be further explored to utilize more cavity modes, aiming to exhibit a wider bandwidth to satisfy the increasing requirement from the modern communication system.…”

Novel Differential-Fed Frequency-Reconfigurable Filtering Patch Antenna for 4G/5G Systems

“…Recently, dual-polarized and differential-fed techniques have been extensively introduced to improve the performance of the microwave and RF systems [28][29][30]. Different differential-fed antennas have been reported, such as planar antennas [31][32][33][34], magneto-electric dipole antennas [35,36], 3D-backed antennas [37], and so on. A differential planar antenna presented in [31] is fed by 0 0 and 180 0 signals, providing low cross-polarization, wide bandwidths, and high gain.…”

Design of Differential-Fed Filtering Patch Antenna with High-Gain and Dual-Polarized Characteristics for 5G Systems

“…"Thus, microstrip antennas with filtering performance, high gain, high isolation, high front-to-back ratio (FTBR), stable radiation pattern, good common-mode (CM) rejection level and unidirectional radiation pattern in the planar configuration simultaneously are necessary for 5G applications [26][27][28][29][30][31]. Recently, dual-polarized and differential-fed techniques have been extensively introduced to improve the performance of the microwave and RF systems [32][33][34]. Different differential-fed antennas have been reported, such as planar antennas [35][36][37][38], magneto-electric dipole antennas [39,40], 3D-backed antennas [41], and so on.…”
