| Abstract | A microstrip quasi-horn antenna for UWB radars and sensors has been developed. The antenna achieves good performance in both frequency domain for CW signals from 0.3-6 GHz and time domain for monocycle pulses of various durations. The time-domain measurement, particularly, shows that the antenna can transmit and receive monocycle pulses effectively with minimum distortion, little ringing, and small reflection, clearly demonstrating the signal fidelity of the antenna in reproducing the waveform of UWB signals which is critical for UWB radars and sensors. For time-domain applications, such as UWB radars which transmit and receive pulse signals, characterizing the antenna's transient responses directly is useful and important for accurate assessment of its signal fidelity and matching. The developed antenna employs non-uniform microstrip transmission line and has good linear phase, simple fabrication, and easy integration with microwave integrated circuits. It requires no transition or balun at its input, leading to wide bandwidths and high operating frequencies. The antenna has been successfully used in several UWB surface-penetrating radars. |

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.
