| Abstract | A new, hybrid, nona-band antenna of the size 80 × 8 × 5 mm3 is proposed for recent metal-rimmed smartphone applications. The proposed design is composed of a metallic frame (external antenna) and an internal radiating structure. The proposed antenna is attached to the top part of the smartphone. It uses a microstrip feed as a direct coupling line for the internal radiating structure. The feed also represents a capacitive coupling feed for the overall metal-rim antenna structure. The metal rim with a small gap of 2 mm is connected to the system printed circuit board by two grounding points. The proposed antenna excites four coupled loop modes, three slot monopole modes, three dipole modes, and one monopole mode. By incorporating the excited modes, the proposed antenna covers all recent smartphone applications in the frequency range between 0.79 and 6.0 GHz. The proposed design is described with great details and both simulated and measured results are used to establish its validity. The antenna performance with mobile phone components is also investigated. The results demonstrate that the proposed antenna represents an excellent candidate for applications such as GSM850, GSM900, GSM1800, GSM1900, UMTS2100, LTE2300, LTE2500, LTE3500, and WiFi5500 bands. |

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.
