| Abstract | Since the FCC legalized the operation of ultra-wideband (UWB) enabled products in the US, many novel, very broadband antenna designs have emerged. The paper discusses the cable-current effects of a common, miniature printed monopole antenna with a shaped ground plane and of a miniature printed dipole antenna. A CPW-fed pseudo monopole antenna is used to demonstrate that cable currents affect the low frequency performance when the antenna is fed by a coaxial line. A UWB dipole antenna is presented with significantly reduced cable-current effects. It is fed with a CPW line which transitions rapidly into a CPS line. The surface area of the PCBs for the dipole and the pseudo monopole are about the same. It is shown that using a balun and avoiding a finite-sized ground plane reduce the effect of cable currents on the antenna performance. |

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.
