| Abstract | Few low-profile VHF/UHF antennas have been reported so far although they are demanded in many applications such as aircraft communication systems. In this letter, a low-profile wideband VHF/UHF antenna based on the conventional discone antenna is proposed. It is composed of a discone antenna that is flattened with additions of a cavity-backed discone, a short-circuited configuration, and a two-plate top structure. The simulation results show that the addition of the three structures makes the proposed antenna low-profile and wideband. A prototype with optimized geometrical parameters was fabricated and tested. The measurements show that the prototype has a VSWR bandwidth of 76% from 200 to 447 MHz, a height of only 0.087λmax, and a radiation pattern of omnidirectivity. The designed antenna has great potential for its flush-mount capability. |

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.
