| Abstract | The authors present design of a printed log-periodic trapezoidal dipole array (PLPTDA) antenna with a balun-feed operating throughout the 2–18 GHz frequency range. For this purpose, the antenna is designed and simulated in the CST Microwave Studio environment. Thus, better directivity along the operation bandwidth is achieved via the iterative simulations with a 33.33% reduction in the dipole length at the lowest frequency 2 GHz as compared with the counterpart standard log-periodic antennas. Furthermore, they fabricated the PLPTDA antenna with and without the balun-feed. Thus, influence of the balun on the performance is investigated and the average gain of the PLPTDA antenna with the balun-feed is measured as 8.16 dBi provided voltage standing wave ratio (VSWR) < 2, which agrees with the simulation results. Furthermore, these measured gain/directivity results are compared with the counterpart antennas' measured performances in the literature considering their operation bandwidths and sizes. It can be concluded that their proposed PLPTDA antenna will prove to be useful in both wideband civilian and military applications in the S, C, X, and Ku bands within the 1:9 ultra-wideband bandwidth which is the largest achieved in this class antenna technology in the literature up to now. |

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.
