چکیده مقاله :

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.

چکیده انگلیسی:

In this paper, the improvement of the radiation pattern and the properties of multi-band trapezoidal fractal antenna with self-complementary layers have been investigated. The antenna is excited by a microstrip feed-line with two sub-layers to increase bandwidth and improve the radiation pattern. The dual-layered complementary arrangement has had positive effects on the resonance frequencies and improved the properties of the radiation patterns. This antenna offers a good efficiency, suitable bandwidth, and radiated pattern in a designed resonance frequency. Six bands (S11<-15 dB), with center frequencies of f1=0.9 GHz, f2=1.57 GHz, f3=1.85 GHz, f4=2.15 GHz, f5=2.5 GHz and f6=3.5 GHz are obtained within the band of (0.5-4) GHz. This antenna offers good efficiency which changes from 70% to 95%. The measurement results clearly confirm the simulation results
