Abstract AR
يتناول البحث طريقتين في التحليل النظري، طريقة مجالات الفتحة (AFM) و طريقة التيارات المحتثه (ICM) تم استخدامها لتحديد مجالات الإشعاع لهوائي قطع مكافئ مغذى بنوعين من الهوائيات الشريطية.
حسابات هياكل و معاملات الإشعاع لهوائي القطع المكافئ عندما يثار سطحه العاكس بهوائي شريطي دائري (CRMA) و هوائي شريطي حلقي مغلق من الخارج (ARMA)، أعطت أفضل نتائج عند اختيار قطر العاكس (D=20λ) و بنسبة (f / D) مأخوذة عند حافة إضاءة بحدود (-3dB).
و بالنتيجة، فإن كلا الطريقتين أعطت توافق تام لهياكل المجالات الإشعاعية في المستويات الأساسية في منطقة المجال البعيد للإشعاع.
Abstract EN
Two theoretical analysis methods ; Aperture Field Method (AFM) and Induced Current Method (ICM), have been studied for obtaining the radiation fields of parabolic reflector antenna fed by two types of microstrip antenna.
Calculations have been made of the radiation parameters and patterns of parabolic reflector, when exciting its surface by Circular (CRMA) and outer shorted Annular(ARMA) Ring Microsrtip Antenna.
These calculations give the best results, for the aperture diameter (D=20λ) and ratio (f / D) that taken at edge illumination about (-3dB).
As a result, both methods are in a complete agreement in studying of radiation patterns in principle planes (E and H) at far-field region
