“…Several antenna design techniques that exhibit multiband or wideband operations have been reported in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] for wireless applications. Amid these designs, dielectric resonator antennas (DRAs) are very popular as they offer high dielectric strength and no inherent conductor loss, which results in better radiation efficiency.…”

“…Even though the patch antenna design in [7] has a size of 34.6 × 33.05 × 1.57 mm 3 and can cover the entire Wi-Fi 5 band, the design has used an expensive Roger substrate to fabricate the antenna. Thus, in [8][9][10][11], several unique antenna designs with very wide bandwidth for specific industry applications are introduced using a low-cost FR-4 substrate. In [8], a multiband shark-fin shorted monopole antenna (of dimensions 57 × 40 × 1.6 mm 3 ) for automotive applications has been investigated.…”

“…However, its hexa-band characteristics can only be achieved by loading a PIN diode located at a reclined L-shaped slot in the ground plane, where the use of the diode can further increase the manufacturing complexity of the designs. To reduce the manufacturing complexity, [10,11] present a simple monopole antenna operating in the 2.4/5 GHz WLAN bands with dimensions of 44 × 33 mm 2 and 42 × 30 mm 2 , respectively. As wireless devices such as smartphones, laptops, notebooks, and tablets play a very crucial role for the end-user in day to day life, several antennas designed for laptop/portable devices are reported in [12][13][14][15][16].…”

A wideband coplanar waveguide (CPW) fed monopole antenna designed for Wi-Fi 5 and Wi-Fi 6 applications is proposed. The proposed antenna (main radiator) has a designed footprint of only 20 × 8.7 × 0.4 mm 3 , which is composed of an oval-shaped ring radiator with three concentric rings and a double-T structure loaded with a J-shaped slot. The main novelty of this work is that the measured wideband operation of 34.5% (5.15-7.29 GHz) is contributed by only a single resonance at 6.2 GHz, conforming to the bandwidth requirement of and . Furthermore, the proposed antenna also exhibits good radiation characteristics, including a gain around 2.25 dBi, a radiation efficiency above 80%, a total efficiency above 70%, and omnidirectional radiation patterns with a low magnitude of cross polarization throughout the bands of interest.

In this paper, dual-band split ring monopole antenna structures for 5G sub-6 GHz and WLAN applications are proposed. The antenna structures are designed from a rectangular annular ring monopole antenna. A compact dual rectangular split ring monopole antenna is designed to operate over dual bands. The two split rings are connected through a common arm. The structure is optimized to provide S 11 ≤ −10 dB over 3.3-3.6 GHz and 5.15-5.5 GHz for 5G and WLAN applications. In the second dual-band antenna, a slot is cut in one of the arms to form another closed rectangular ring to further reduce the dimensions of the antenna. This structure provides S 11 ≤ −10 dB over 3.3-3.6 and 5.5-5.9 GHz for 5G, WLAN and V2X applications. The two bands can be easily controlled as the dimensions of two rings determine the resonant frequencies of the two bands, and one of the arms of a ring is unresponsive to lower band and affects upper band only. Both antennas offer nearly omnidirectional radiation patterns in both bands. The two prototype antennas are fabricated on a 0.17λ 0 × 0.19λ 0 and 0.15λ 0 × 0.19λ 0 FR4 substrate, where λ 0 is the free-space wavelength corresponding to 3.3 GHz. The measured results agree with the simulated ones.

In this paper, a low profile compact 8‐port multiband antenna with polarization diversity principle for automotive communication is proposed. The geometric of the proposed MIMO antenna is integrated with multiple stubs on substrate having a size of 0.94λg × 0.94λg. The proposed design resonates at multiple frequencies of 1.8, 2.4, 5.2, and 5.8 GHz, respectively for GSM, ISM bands and WLAN wireless services which covers the bandwidth of 2.8%, 5%, 5%, and 5.6%, respectively with S11 ≤ −10 dB. Besides, the measured results provide a peak gain of 4.3, 3.1, 4.5, and 4.2 dBi at 1.8, 2.4, 5.2, and 5.8 GHz, omni directional radiation pattern with more than 80% of efficiency in all operating bands. The MIMO structure provides a good isolation of greater than 20 dB without decoupling structure, envelope correlation coefficient of ≤0.1, diversity gain of ≥9.99 dB, mean effective gain of <1 dB, total active reflection coefficient ≤−10 dB, channel capacity loss of ≤0.25 bits/s/Hz. Finally, the housing effect of MIMO antenna is analyzed in the vehicular environment which provides good performance for Vehicular to Intravehicular communication.
