Study of Impedance Matching in Antenna Arrays Due to Total Radiation

Résumé

The phenomenon of impedance mismatching in antenna arrays is a potential source of performance degradation, particularly when huge number of antenna elements are placed side by side. Therefore, from its noticeable impact on the performance of communication components and systems, arose the necessity of studying the phenomenon of mismatching so as to minimize its effect. However, in an array of antennas, each antenna appears to be matched when measured individually. Nevertheless, the problem of mismatching reveals itself strongly when the whole array is set to radiate. The value of the input impedance of individual antenna elements changes versus antenna number and position. In this research, the impact of total radiation from an array on input impedance of individual antenna elements is analyzed through theory. The obtained results are compared through simulations and measurements.
