چکیده مقاله :
در این مقاله یک آنتن چهاربانده میکرواستریپی با استفاده از ساختارهای متامتریال ارائه شده است. آنتن پیشنهادی در این مقاله، دارای یک ساختار نامتقارن بوده و از دو المان تشعشعی یکسان و یک صفحه زمین در قسمت پشتی تشکیل شده است. در این طراحی، هر المان تشعشعی از یک خازن متقابل تشکیل شده است که در انتها به یک پچ مثلثی شکل تشعشعی با شکاف‌های دایروی وصل می‌شود. آنتن پیشنهادی دارای ابعاد مینیاتوری به‌صورت 15×10 میلی‌متر مربع است. همچنین آنتن پیشنهادی دارای چهار رزونانس در فرکانس‌های 19/3 گیگاهرتز (%25/1)، 22/6 گیگاهرتز (%74/10)، 18/7 گیگاهرتز (%19/5) و 12/9 گیگاهرتز (%52/4) است. پترن و بهره آنتن در فرکانس‌های رزونانس قابل‌قبول می‌باشد. آنتن پیشنهادی ساخته شده و در آزمایشگاه آنتن مورد آزمایش‌های عملی قرار گرفته است. نتایج حاصل از آزمایش‌ها در مقاله ارائه شده و همخوانی خوب و مناسب بین نتایج تست و شبیه‌سازی، صحت و کارایی طراحی آنتن مایکرواستریپی چندبانده پیشنهادی را تأیید می‌کند.
In this paper, a four-band microstrip antenna using metamaterial structure is presented. The antenna proposed in this article, has an asymmetric structure and it is made up of two identical radiation elements and ground plane at the back. In this design, each radiation element consists of a reciprocating capacitor, which is attached to a slotted triangular acetate at the end. The proposed antenna has a miniature dimension of 10×15 mm2. Also the proposed antenna has four resonances in frequencies of 3.19 GHz (1.25%), 6.22 GHz (10.74%), 7.18 GHz (5.19%) and 9.12 GHz (4.52%). Pattern and gain of the antenna are acceptable at resonant frequencies and the good consistency between the test result and the simulation confirm the accuracy of the antenna design. The proposed antenna is made and tested in the antenna laboratory. The results of the measurements are presented in the paper. Good consistency between test and simulation results confirms the accuracy and efficiency of the proposed multirole microstrip antenna design.
