Antenna array decoupling and descattering

About this Research Topic

As more and more 4G, 5G, and 6G systems will be supported by a common wireless communications platform, antenna real estate will become increasingly scarce. Consequently, the number of antenna elements on any platform, being either a mobile terminal or base station, will continue to increase. Correspondingly, the spacing between antenna elements servicing either the same bands or different bands will become smaller. This smaller distance typically results in two problems, namely: strong mutual coupling and distortion of the radiation patterns of the elements.

It is well known that electromagnetic interference exists among antennas placed in close proximity. This electromagnetic interference causes high correlations among the signals received by the different antennas. It introduces unacceptable distortions of their radiation patterns and degradation of their impedance matching performance. The net result is a complete deterioration of the overall performance of a communication network. Negative effects include a reduction of the data rate, channel capacity and coverage. Reducing unwanted electromagnetic interference is one of the most significant challenges faced by an antenna designer. To better address this scientific and engineering issue, one needs to recognize that there are two different types of electromagnetic inferences involved, i.e., mutual coupling and scattering, and each needs to be addressed systematically, but differently. The goal of this Research Topic is to solve the two problems at the same time.

Topics of interest include but are not limited to:
• In-band and cross-band mutual coupling reduction in multi-band antenna arrays
• In-band and cross-band scattering suppression in multi-band antenna arrays
• Mutual coupling reduction between two polarizations of dual-polarized antennas


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
