ملخص المقالة :

در این مقاله بهبود الگوی تشعشعی و خواص چند بانده آنتن فراکتال ذوزنقه‌ای با لایه‌های خود مکمل، مورد بررسی قرار گرفته است. تغذیه آنتن توسط خط مایکرواستریپ و با دو زیر لایه، برای افزایش پهنای باند و بهبود پترن تشعشعی ایجاد شده است. طبقه بندی دو لایه مکمل باعث اثرات مثبت در فرکانس تشدید و بهبود پترن تشعشعی شده است. این آنتن بازدهی، پهنای باند و الگوی تشعشی مناسبی، در فرکانسهای تشدید طراحی شده ایجاد کرده است. شش فرکانس تشدید با افت برگشتی کمتر از 15 دسیبل (S11 کمتر از 15- دسیبل) در محدوده فرکانسی 5/0 تا 4 گیگاهرتز به‌دست آمده است. نتایج حاصل از اندازه‌گیری صحت نتایج به‌دست آمده از شبیه‌سازی را به وضوح تایید می‌کند.
