Measurements of test antennas are performed on antenna ranges. The operated microwave far-field outdoor range was built-up in 1970's and therefore it was not appropriate for the today measurements. Thus, it was decided to perform the complete reconstruction and testing. Some results of new ample measurement campaign are just given. The optimization of antenna range using merely measurement is very inefficient, and therefore that is done by numerical simulations. Consequently the paper surveys briefly electromagnetic wave propagation over irregular terrain. The physical optics approximation of vector problem was chosen. That allows the comparison of selected numerical simulations and measurements for the reconstructed far-field range. A possibility of antenna range optimizing by using numerical simulation considering various constraints is verified.
This article is focus on design and realization of measurement system for testing far-field patterns of phased array antennas. The task was a test and correction of the transmitting and receiving phased arrays antennas of high transmitting power in X-band. Such antenna and measurement system have been built and pattern properties of antenna has been tested with use this system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
