| Abstract | Here, a new design of phased-array antenna for future fifth-generation mobile phone applications is presented. The proposed phased array consists of 12 dual-band circularly polarised antenna elements at 28/38 GHz used to form a linear array in the edges region (top-side, right, and left sides) on a mobile phone circuit board. The measured and simulated results show that the designed antenna element has a reflection coefficient less than −15 dB in the assigned frequency bands of 28/38 GHz with a realised antenna gain of 7.68 and 7.73 dB, respectively. Furthermore, the performance of the array antenna package in the vicinity of user's head–hand has been investigated in this study at different scenarios. The designed array antenna achieved good matching impedance with high isolation between the array elements. Moreover, an acceptable realised gain of 16.85 dB on average with an axial ratio <3 dB is obtained in the entire operation bands. Lastly, the metrics of total scan pattern, coverage efficiency, and user shadowing are investigated. It is found that the proposed phased-array antenna has good 3D beam-steering characteristics, which makes it suitable for millimetre-wave 5G mobile applications. |

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.
