Design of Compact Rotman Lens Using Truncated Ports With Energy Distribution Slots

Design of Rotman Lens Antenna at Ku-Band Based on Substrate Integrated Technology

In this research work, a multibeam antenna which is a combination of a beamformer network (BFN) and a linear array antenna, has been designed. A Rotman lens has been chosen as beamformer network and Vivaldi antennas have been selected for constructing array antenna. The Substrate Integrated Waveguide (SIW) was used for implementing Rotman lens. After explanation the structure of Substrate integ...

rotman lens

آرایه فازی به منظور هدایت بیم در راستایی خاص نیازمند شبکه تغذیه ویژه ای می باشد. رتمن لنز به عنوان یکی از این ساختارهای تغذیه با قابلیت تحریک چند بیم در زوایای متفاوت در یک زمان، استفاده گسترده ای پیدا کرده است. در این پژوهش مهم ترین عوامل موثر بر پهنای باند این شبکه در ساختار مایکرواستریپ، که شبکه تطبیق امپدانس، رفتار انتشاری موج در بخش صفحات موازی و خطای فاز خطوط انتقال می باشند، بررسی شده و ...

Novel Compact, Dual Frequency FSS Design using Patch with Annular Rectangular Slots

In this paper, a complete design and analysis of the frequency selective property of an array of patches with annular rectangular slots is presented. It is observed that there is a tremendous decrease in resonance frequency as the annular rectangular slot is made on the patch and it is also seen that, with the incorporation of another annular rectangular slot, FSS is resonant at dual frequencie...
