Design and analysis of millimeter wave double F slot patch antenna for future 5G wireless communication

A Novel High Gain Monopole Antenna Array for 60 GHz Millimeter-Wave Communications

“…By investigating the performance of the proposed monopole antenna shown in Figure 5, it is evident from Figure 11 that a bandwidth of 2.38 GHz was achieved with a return loss of −24.12 dB at the resonance frequency. As previously mentioned in Tables 1 and 2, the bandwidth was enhanced from 1.15 GHz, which was obtained by using iteration 1 with ground 1, to 2.38 GHz obtained when using iteration 5 with ground 4, which presented the effect of introducing the DGS on the antenna performance, as well as applying different techniques on the patch; these techniques performed on the patch and the ground plane caused the proposed single antenna to have a wider bandwidth than that achieved in [25] by an increase of 5.24% in the same band. Figure 12 presents the radiation characteristics of the single patch antenna for 5G operation; the 2-D and 3-D radiation patterns were carried out at 60.5 GHz.…”

On the Efficiency of the Advanced TWA Approach to the 60-GHz Microstrip Antenna Analysis for 5G Wireless Communication Systems

“…In [19], the authors proved the efficiency of a 60GHz virtual loop antenna built on low resistivity silicon substrate. These antennas have been fabricated and designed in different shapes, such as rectangular, circular, helical [20], double F-slot [21], double U-slot [22], T-slot [23], E-and H-slots [24]. Moreover, the feasibility of 5G connectivity beyond 70GHz was demonstrated using an experimental prototype in [25].…”
