| Abstract | In this letter, the zeroth-order and TM10 modes of composite right/left-handed (CRLH) mushroom resonator are investigated with regards to the number of cells. It is shown that in addition to 2N - 1 metamaterial resonance frequencies in an N-cell mushroom resonator, there is also a resonance which belongs to TM10 mode of the unit-cell. This TM10 mode is the fundamental mode of the patch which occurs at a frequency above metamaterial resonance frequencies. These two types of resonance frequencies yield 2N resonances in an N-cell CRLH mushroom resonator. This is beneficial especially in one-unit cell case due to dual-band operation. To investigate this feature, three types of mushroom resonant antennas with different number of cells (N = 3, 2, 1) are designed and implemented. Based on theoretical investigation, a single-cell dual-band CRLH mushroom resonant antenna is proposed. At the zeroth-order mode (2.88 GHz), the proposed antenna has a dimension of approximately 0.19λ×0.09λ×0.014λ while achieving a gain and an efficiency of -0.82 dBi and 46%, respectively. |

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.
