| Abstract | This study addresses the modelling of a dual band (28 and 38 GHz), circularly polarised slotted-patch-antenna for highly demanded millimetre wave multi-input multi-output (MIMO)-systems in fifth generation (5G) networks. A computer-aided-design model is derived by means of an artificial neural network (ANN) which allows obtaining the physical dimensions of a single-fed antenna, satisfying both near- and far-field goals, without resorting to time-consuming electromagnetic simulation. This mathematical model can be implemented in any CAD-tool, as demonstrated within the framework of advanced design system. This allows, for the first time, to carry out optimisations of strategic importance for future 5G non-linear-radiating-systems, especially operating at millimetre wave, directly addressing their far-field behaviour. The model performance is validated by some examples and measurement results. A further important advantage of this approach is that the trained ANN-model can be further adopted to fast, but accurately, investigate the complex relationships between antenna layout and its near-field and far-field performance, such as the resonance conditions and the polarisation behaviour. Indeed arbitrary orthogonal-polarisations (LHCP/RHCP) have been achieved by the aid of the ANN-model of the same topology. This result can be adopted to implement a combination of two independent radiation patterns for the antenna pair: this feature is attractive for MIMO applications. This is confirmed by measurements showing antenna-coupling reduction with the MIMO-array exploiting polarisation diversity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
