| Abstract | This paper considers utilization of meandered (serpentine) microstrip lines as feeds in planar multylayer phased array antennas. Nevertheless, that these structures have radiating properties itself and they are used as travelling-wave antennas [1], however, they can be optimized to have predictable performances as antenna feeds in respect of transmitted phase and magnitude. Substantial problems of these lines, the resonance attenuation and phase delay can be avoided with properly chosen resonance ¿-junction length of the serpentines. The paper contains results from numerical optimization of regular and non-regular meandered feeds obtained by MoM-based simulator and compared with measurements in Ku-band. Finally, design rules are formulated for meander parameters that allows of avoiding resonance losses and unpredictable phase delay of antenna feeds in desired frequency range. |

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.
