ملخص المقالة :

در این مقاله یک رویکرد جدید برای طراحی سطوح انتخابگر فرکانس معرفی شده است. ما سعی می‌کنیم تا پاسخ فرکانسی مطلوب خود را با استفاده از تنظیم پاسخ فرکانسی هر سطح تشکیل‌دهنده، بسازیم. همچنین در این مقاله یک سطح انتخابگر فرکانس مینیاتوری دو بانده پیشنهاد شده است. در مقایسه با تکنیک‌های طراحی سنتی ساختار ارائه شده دارای مزیت غیر رزونانسی بودن عناصر سلول واحد، با ابعاد مینیاتوری می‌باشد. سلول‌های FSS پیشنهادی از دو سطح خازنی و سلفی تشکیل شده است که مانند یک فیلتر دو بانده در مقابل عبور امواج الکترومغناطیسی عمل می‌کند. عملکرد این ساختار برای زوایای مختلف تابش و پلاریزاسیون پایدار می‌باشد
