| Abstract | Dielectric Image Guide (DIG) is a convenient planar structure for low cost millimeter wave (MMW) circuits and antenna arrays. Exciting the DIG is important in some applications such as active antenna array and beam forming. The Dielectric Resonator (DR) is a conventional approach for coupling the excited mode to the DIG. Furthermore, we should find a proper way for making an oscillation in structure consisting of DIG and DR. So, the oscillator concept should be considered properly. Among semiconductor sources, Gunn oscillators have shown to be promising as low cost, simple and high power alternative in mm-wave and Terahertz range. It is also compatible configuration for this kind of antenna array. Conventionally, the oscillation frequency is stabilized by a cavity waveguide resonator [1]. At (sub) mm-wave wavelength, however, the waveguide cavity becomes impractically small in size and extremely sensitive to fabrication tolerances. To overcome this shortcoming, in this paper, we propose to stabilize the oscillation frequency through direct interaction of the Gunn diode with a whispering gallery mode (WGM) dielectric resonator (DR). The dimensions of a WGM resonator can be much larger than the operating wavelength [3], and therefore less sensitive to fabrication tolerances. In order to transmit the generated mm-wave signal to an external load, the structure is coupled to the DR. The proposed configuration is structurally capable to be integrated with three dimensional waveguide structures such as DIG or planar guiding like CPW or microstrip line. |

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.
