| چکیده | ||
| در سالهای اخیر ساختارهای محفظه تشدید فبری پروت برای افزایش جهتدهی در آنتنها مورد توجه قرار گرفته است. محفظه تشدید، از یک صفحه زمین به عنوان بازتابنده کامل و یک صفحه رولایه به عنوان بازتاب کننده ناقص تشکیل شده است. در این مقاله از سلول واحدهای فرامواد به عنوان صفحه بازتاب کننده ناقص و از آنتن میکرواستریپ به عنوان آنتن تشعشع کننده اصلی در محفظه تشدید فبری پروت بهره گرفته شده است. همچنین تاثیر استفاده از فرامواد در رولایه آنتن فبری پروت بر روی پارامترهای تشعشعی آنتن به صورت استفاده از چند رولایه مختلف در محفظه تشدید فبری پروت بررسی شده است. در نهایت به عنوان یک طرح جدید با کارایی تشعشعی بهتر آرایهای از سلول واحدهای امگا برای رولایه پیشنهاد و طراحی شده است. سپس کارایی آنتن تشعشع کننده با این رولایه با رولایهای از سلول واحدهای پچ و حلقههای شکافدار تشدیدی مقایسه شده است. شبیهسازیها با نرم افزار CST-Microwave Studio انجام شده و با استفاده از نرم افزار Ansoft HFSS صحت نتایج حاصل بررسی و تایید شده است. | ||

| چکیده [English] | ||
| Recently Fabry-Perot (FP) resonator structures for enhancing directivity have found wide use in antenna design. FP Resonator antenna generally consists of primary radiator backed with a metal ground plane and a partially reflective surface (PRS). In this paper metamaterial unit cells is utilized as PRS in FP cavity for increasing microstrip antenna directivity. As a novel design an array of Omega unit cells is proposed and designed. FP antenna performance with Omega cover and superstrate of patch and SRR is simulated and compared. For validation of purposes, the antenna is designed and simulated through using of two different 3D full-wave electromagnetic simulation tools CST Microwave Studio and Ansoftâs High Frequency Structure Simulator (HFSS). | ||
