| Abstract | In this letter, a miniaturized C-band phased-array antenna based on a novel series-fed network is introduced. The series-fed network, radiating elements, and phase shifters are the main parts of the proposed phased-array antenna. In order to use the identical phase shifters, quarter-wavelength transformers are used in the design of the series-fed network. Furthermore, by choosing the proper place of the quarter-wavelength transformers, the distance between adjacent radiating elements is significantly reduced to 0.33λ0. To reduce mutual couplings between radiating elements, miniaturized negative-order substrate integrated waveguide (SIW) slot antennas are chosen as radiating elements. A low-cost and compact 4-bit composite right/left-handed (CRLH) phase shifter is used due to the capability of being placed in a series-fed network. The proposed low-cost phased-array antenna is fabricated on a single-layer printed circuit board (PCB), and good agreement between the simulation and measurement results is obtained. The beam scanning range is 38°, and the impedance bandwidth of the phased-array antenna is 25 MHz at the center frequency of 5 GHz. |

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.
