Abstract AR
وجود مستوى عالي من الحزم الجانبية للإشعاع في الهوائي غير مرغوب فيه كما إن أداء الهوائي و كفائتة سوف تنخفض بصورة كبيرة، تركيب الهوائي خصوصا في شكل المصفوفة له القابلية لتقليل التداخل و تحسين سعة القناة و توسيع مدى تغطية الإشارة.
في هذا البحث IWO تم استعمال لتحسين مواقع العناصر الداخلية في الهوائي الخطي و لغرض الحصول على نمط الإشعاع المطلوب الذي يلغي الحزم الجانبية الغير مرغوب فيها.
و قد استخدمت خوارزمية IWO بنجاح في تحديد المواقع الدقيقة للعناصر الداخلية للهوائي.
وجدت النتائج إن خوارزمية IWO أنها قادرة لإيجاد الحلول المتميزة في اغلب الحالات مع أداء متميز على حساب الطرائق التقليدية.
Abstract EN
The presence of large sidelobe radiation beam levels of an antenna is undesirable as the antenna performance and efficiency will be greatly degraded.
Antenna structures especially in array arrangements have the capability to provide interference reduction, improvement of the channel capacity and expanding the range of a signal's coverage.
In this paper, Invasive Weed Optimization (IWO) is utilized to optimize the inter-element position of even-element linear antenna arrays (LAA).
The objective is to produce as close to desired radiation pattern as possible that exhibits sidelobe level (SLL) suppression.
The IWO algorithm can be successfully used to locate the optimum element positions based on symmetric and even-element LAAs of isotropic radiators.
The results obtained showed that the IWO algorithm is capable of finding the optimal solution in most cases with superior performance over conventional method
