| Abstract | In this study, an internal antenna integrated into a 49-inch TV model is presented, operating in the ultra-high frequency (UHF: 470‒771 MHz) band for signal reception in ultra-high definition television (UHD-TV) applications. The design of the proposed antenna has encountered major challenges such as relatively narrow impedance bandwidth, limited space, the effect of material properties, and the electromagnetic interference from the other components inside the TV that deteriorate the performance of the antenna considerably. The antenna is positioned directly on the bezel frame (made of polycarbonate-acrylonitrile butadiene styrene: ԑ r = 3.5, tan δ = 0.005) of the TV model as the substrate for the antenna. A monopole-type antenna is chosen to easily implement along the long side of the bezel frame in a very narrow spacing between the display and the casing of a TV (∼2.5 mm). Combined with a sleeve feed, tapered line, and parasitic strips, the proposed internal antenna exhibits a wideband impedance characteristics. The measured results show that a radiation efficiency of higher than 70% and a peak gain of 4.8 dBi are obtained over the operating frequency range of 430‒940 MHz (relative bandwidth of 75%), which cover the entire UHF band. These results indicate that the proposed antenna is very suitable for UHD-TV 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.
