| Abstract | Recently the planner antenna technology is emerging due to the interesting demands for wireless communication of the ubiquitous society. The advantages of planner antenna over the other antenna types such as dipole, loop etc. are that, it is low cost, low profile and easily integrated with active components [1]. However the conventional microstrip antennas have some drawbacks such as narrow bandwidth, low gain etc. Several works have been done for increasing the gain of the antenna such as using the array technology. In this paper, a novel single fed orthogonal linear polarization switchable microstrip array antenna with enhanced gain is proposed. The structure based on the parasitic array technology [2] is used for the gain enhancement. The antenna consists of a fed patch and four parasitic patches. Four switching diodes are loaded on the corners of the fed patch to control the surface current. The proposed array antenna can switch the polarization axis to ±45deg. by controlling the surface current. The orthogonal transmission and reception function of conventional antenna is generally fixed, because of the absence of the switching function. If the switching function is possible, the design flexibility of the radio system will be much more expanded [3]. In order to realize ±45deg. orthogonal linear polarization controllable microstrip array antenna; four switching diodes are mounted on the corners of the fed patch. The FDTD method introduced by Yee [4] is used to simulate the antenna which is followed by the experimental investigation. |

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.
