چکیده مقاله :
در این مقاله ساختار جدید و فشرده ای از آنتن یک جهته که از یک دوقطبی الکتریکی صفحه ای و یک المان اتصال کوتاه شده تشکیل شده، معرفی می‌شود. این آنتن توسط یک خط تغذیه Γ شکل تحریک می گردد. پهنای باند امپدانسی عریضی در بازه فرکانسی 3/1 گیگاهرتز تا 3 گیگاهرتز در عملکرد خروجی این آنتن مشاهده می‌شود. الگوهای تشعشعی پایه دار با سطح گلبرگ اصلی بالا و سطح گلبرگ فرعی و پشتی کم از خصایص دیگر آنتن معرفی شده اند. فرایند طراحی آنتن به صورت پله به پله و پارامتریک بر مبنای مقادیر کلیدی هندسه آنتن صورت پذیرفته است. خصیصه اصلی آنتن مورد نظر، تحقق قطبش دایروی در درصد بالایی از پهنای باند کاربردی است. الگوهای تشعشعی صفحات متعامد E و H همراه با الگوهای قطبش دایروی چپگرد و راستگرد برای آنتن مورد نظر استخراج شده و مورد تحلیل قرار گرفته است. شباهت زیادی میان الگوی صفحه ایE و H وجود دارد که نشان دهنده دقت فرایند طراحی است. از سوی دیگر برای مطالعه حالت قطبش دایروی، نمودارهای چپگرد و راستگرد بر مبنای جهت بیم اصلی و سطح قطبش متعامد دارای عملکرد قابل قبولی هستند. بیشینه بهره کلی آنتن در باند فرکانس طراحی شده نزدیک 10 دسیبل است.
This paper introduces a new and compact structure of a directional antenna consisting of an electric dipole and a truncated connection element. This antenna is fed by a Γ shaped power line. Wide impedance bandwidth in the frequency range of 1.3 GHz to 3 GHz will be observed in the output performance of this antenna. Base radiation patterns with high main loop and low side and back loop level are other features of the introduced antenna. The antenna design process is step-by-step and parametric based on the important parameters of antenna geometry. The main feature of the antenna is the realization of circular polarization at a high percentage of implicational bandwidth. The radiation patterns of orthogonal plates E & H along with left and right circular polarization patterns for the desired antenna have been extracted and analyzed. As predicted, there are many similarities between the E and H plane pattern, which indicates the accuracy of the design process. Is. The maximum total gain of the antenna in the designed frequency band is about 10 dBi..
