Abstract | The main objective of the present study is to improve the bandwidth of the dielectric resonator antenna (DRA). A new four-element multilayer cylindrical dielectric resonator antenna (MCDRA) array above the ground plane is proposed here. MCDRA is easy to design and excited with HE111δ mode excited in each MCDRA by centrally placed dielectric resonator in which TM01δ mode excited. The effect of design parameters such as permittivity of materials, probe height and arrangement of dielectric layers are investigated and the excited modes (i.e. TM01δ and HE11δ) are also been confirmed by simulations. The simulation is performed on Ansoft's HFSS package. The proposed multilayer cylindrical dielectric resonator antenna (MCDRA) can offer an impedance bandwidth of ∼47% for the return loss below −10dB where frequency range is from 4.06 to 6.07 GHz and resonance frequency is 4.3 GHz with monopole like radiation pattern and it is stable in the passband with 4.73 dB gain. |

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.
