“…Another array allowing electronic scanning by changing the phase is focused aperture array. Traditional focused aperture antennas mainly include lens antenna 51 and parabolic antenna 52,53 . However, the complex curved optimal focal arcs and contours of the lenses, as well as the high mass of the employed dielectric lenses, make these quasi‐optic types of beam scanning techniques challenging to design and manufacture 54 .…”

As the application of microwave to radar and 5G communication goes wider, the array beam scanning capability has become an important and popular issue in modern society. Appropriate implementation of beam scanning methods suitable for diverse conditions could provide better performance and help to save costs for a system. Moreover, electronically scanned array has the characteristics of fast beam switching rate, high measurement accuracy and low profile. Thus, discussions on typical electronic scanning approaches are particularly necessary. This paper first presents a review of typical electronic scanning approaches to microwave arrays, such as the phased array, the focused aperture array, the frequency scanning array, and the time modulated array. And then some latest designs in the industry have been introduced. In addition, problems appeared in the application of the phased array and relevant solutions have been put forward. For the rest, some discussions are briefly summarized, as well as some comments on future trend in this field.
