“…The selection of feed network of antenna array for a particular application depends on several criteria e.g. number of simultaneous beams, peak and average side lobe level, power, tunable and instantaneous bandwidth etc [36]. The feed network is broadly classified in space, constrained and hybrid feeds.…”

“…In a series feed, the radiating elements are fed serially while in parallel feed, they are fed in parallel. In a typical series fed array, the input signal is fed from one end while the other end is terminated in matched load [36]. This type of antenna has found interesting applications in mm-wave beam switching arrays [37]- [40].…”

“…However, the performance of the overall system depends on the other components e.g. phase shifters, feed networks and a trade off in selecting the components can be made to achieve the optimum performance with cost minimization [36]. For mm-wave communication system, extra importance is given on the antenna gain (to compensate the high attenuation and path loss), size, and compatibility with other radio frequency modules [70].…”

The enormous growth of wireless data traffic in recent years has made the millimeter-wave (mm-wave) technology as a good fit for high-speed communication systems. Extensive works are continuing from the device to system, to the radio architecture, to the network to support the communication in mm-wave frequency ranges. To support this extensive high data rate, beam forming is found to be the key-enabling technology. Hence, an array antenna design is an extremely important issue. The beam-forming arrays are chosen to achieve the desired link capacity considering the high path loss and atmospheric loss at mm-wave frequencies and also to increase the coverage of the mm-wave communication system. There are diverse design challenges of the array due to the small size, use of large numbers of antennas in close vicinity, integration with radio-frequency (RF) front ends, hardware constraints, and so on. This paper focuses on the evolution and development of mm-wave array antenna and its implementation for wireless communication and numerous other related areas. The scope of the discussion is extended on the reported works in every sphere of mm-wave antenna array design, including the selection of antenna elements, array configurations, feed mechanism, integration with front-end circuitry to understand the effects on system performance, and the underlying reason of it. The new design aspects and research directions are unfolded as a result of this discussion.INDEX TERMS Mm-wave communication, antenna array design, array configuration, feed mechanism, RF circuit.
