In order to use shared aperture antenna technology for Synthetic aperture radar, communication, Satellite communications, Electronic warfare and all radar applications (e.g., Space borne, aircraft telephony performances, antenna designs, wireless communications, airborne systems), studying the nature and characteristics of the shared aperture antenna technology is important. The purpose of this paper is to review and discuss various techniques aimed to develop the shared aperture antenna subsystem. This paper further focuses on the review of future implementation techniques and performance comparison along with their applications. This review serves as a comparative studies and reference beneficial for shared aperture antenna technology researchers and for future implementation of the technology. This review paper opens a corridor for researchers to perform future studies between different configurations and system models as a reference point for developing more powerful, flexible and efficient applications. © 2017 Eastern Macedonia and Thrace Institute of Technology.
