“…In mm-wave 5G communications, tracking of receivers at different locations is very essential. Several papers have made unrealistic assumptions that the users/receivers channel state information (CSI) is accessible at the transmitter [27,[37][38][39][40]. However, these assumptions are impractical.…”

“…The authors in [33][34][35][36] discussed the applications of FDA in radar. Also, FDA antennas have been utilized in wireless communications for security applications [27,[37][38][39][40] and very recently, FDA antennas in wireless applications were presented in [15,41]. Again, in the application of codesign radar and communication (RadCom), FDA has been very attractive [42][43][44][45][46].…”

With the massive growth of wireless data in mobile broadband communications, millimeter-wave (mm-wave) communication is an alternative enabling technique for fifth generation (5G) wireless communication systems. More importantly, mm-wave offers large frequency spectrum bands ranging from 30GHz to 300GHz that can be utilized to provide very high capacity (i.e., multigigabits per-second data rates). Moreover, because of the small wavelength at mm-wave frequencies, we can exploit large antenna elements in a small physical area, meaning beamforming schemes are feasible. Nevertheless, high directional antennas should be used due to overcoming the severe path loss and absorption in mm-wave frequencies. Further, the antennas should be steerable in angle and range directions to support point-to-point (multipoint) communications. So far, mm-wave communication has utilized phased-array antennas arrangement which is solely angle dependent. This review paper presents recent array technology, namely, frequency modulated frequency diverse array (FDA) for mm-wave communication applications with an emphasis on beamforming. In FDA, small frequency increment is added across the elements. In doing so, an array beam is generated which is angle-range-time dependent without the need of phase shifters. This feature has several promising potentials in mm-wave communications. In this review, the object is to bring to the fore this advance FDA technology to mm-wave communications community to call for more investigations. We review FDA research progress up to date and highlight the potential applications in mm-wave communications.

“…Owing to the favorable characteristic that the beampattern is both range and angle dependent, FDA technology, in recent years [10]- [16], has been applied into DM synthesis for wireless PLS transmissions. Specifically, the authors in [10] achieved directional modulation synthesis using the FDA with linearly increasing frequency increments. The FDA with symmetrically and non-linearly increasing frequency increments was used in [11] to decouple range and angle dependent transmit beampattern for wireless DM transmissions.…”

“…The above-mentioned FDA-based DM schemes [10]- [16], however, mainly focused on wireless PLS transmissions in single-path environments without considering multipath effects. Although some works explored the multipath characteristics of the FDA, such as [17], they did not provide any investigations about the possibility of applying the FDA method into DM transmissions in such multipath environments.…”

A two-ray multipath model for frequency diverse array (FDA)-based directional modulation (DM) is proposed in multi-input single-output multi-eavesdropper (MISOME) wiretap channels for the first time. The excitation factors of the FDA and the weighting coefficients of the inserted artificial noise (AN) are jointly designed in a way which imposes no impact on the desired receiver while simultaneously distorting the received signals of eavesdroppers. Secrecy rate is analyzed for the proposed two-ray multipath FDA-based DM model. Numerical simulations verify the capability of physical layer secure (PLS) transmissions of the proposed FDA-DM model in two-ray multipath MISOME wiretap channels.
