| Abstract | In this study, a new type of horizontal radiation blade structure is proposed and applied to the very high frequency (VHF) broadband whip antenna. The influence of the radius, length, number of branches of horizontal radiation blade and its distribution on the whip body on the electrical performance of the whip antenna is analysed separately to design a more suitable structure, and then an algorithm optimization of single loading and broadband matching network is carried out for further impedance matching. The simulation and measured results both show that compared with the existing broadband whip antenna, the gain and efficiency of the proposed antenna are significantly improved while maintaining a good voltage standing wave ratio (VSWR) over the frequency band of 30–300 MHz, all the VSWR are <3 with an average value of 2.0; all the maximum gain are >−3.5 dB, with an average value of 2.2 dB; and all the efficiency are >15%, with an average value of 47.7%; the pattern deviation in higher frequency is also suppressed to some extent. The proposed antenna has small size, wider bandwidth and higher radiation performance, which is suitable for vehicle-borne and ship-borne VHF communication. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
