Based on the network theory, the equivalent parameters of a comparator cascaded with a two elements array in the single-axle monopulse radar are obtained. The influence of the reflection and coupling of the antenna elements to the reflection character of the SUM and DELTA ports of the monopulse system is studied. The results show that beside the reflection of the elements, the coupling between elements...
A precise knowledge of the electromagnetic receiving characteristics of the antenna is mandatory for a precise determination of the directions of the impinging signals. For circular arrays the phase-mode description is an effective way of approximating the receiving characteristics of the antenna elements. For antenna elements, which are mounted in front of a cone-shaped reflector, angular ranges...
Mutual coupling is an important factor for the study of multiple-input multiple-output antenna system. A study of the effect of mutual coupling between the antenna elements of MIMO system has been performed. We focus on the userpsilas spectral efficiency and data throughput where coupling environment is present. A key contribution of this paper is a simple MIMO structure that offers higher spectral...
The results presented here suggest that there is a correlation between receive coupling and terminal current behavior in a phased array. Therefore, receive coupling can be used to design antenna elements, which will exhibit reduced mutual coupling effects when operated in a phased array. Since only two antenna elements are involved, this is much less computationally intensive than the calculation...
