| Abstract | Here, a novel geometry of dual-band polarisation reconfigurable patch antenna is presented. The proposed prototype design consists of two orthogonal arms as a patch, an inclined slotted asymmetric pentagonal-shaped ground plane and a PIN diode with a biasing circuit. The polarisation reconfiguration is controlled via ON/OFF states of the PIN diode. The unique feature of the proposed antenna design is that it provides polarisation reconfiguration without considerable deviation in −10 dB impedance bandwidth (IBW) frequency response. The proposed antenna has a measured −10 dB IBW of 49.28% (3.96–6.55 GHz) and 41.47% (4.3–6.55 GHz) in the ON-state and OFF-states of the PIN diode, respectively. In the ON-state of the PIN diode, the antenna exhibits a dual-band circular polarisation. The first 3 dB axial ratio (AR) band is 4.5% (4.3–4.5 GHz) and the second 3 dB AR band is 17.69% (5.1–6.09 GHz). The proposed antenna exhibits almost uniform gain over the entire operating axial-ratio bandwidth, with peak CP gain of 2.8 dBic. The suggested antenna has a wide −10 dB IBW, and it is suitable for C-band wireless applications. |

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.
