چکیده مقاله :
در این مقاله تلاش بر این است آنتنی طراحی شود تا در کاربردهای مختلف راداری و مخابراتی مورداستفاده قرار گیرد. توجه به تشعشع آنتن در دستور کار قرارگرفته و بر روی تشعشع آنتن‌ها و همچنین پترن تشعشعی آن‌ها مطالعاتی انجام‌گرفته است حال با توجه به اینکه خاصیت پترن با ویژگی پره‌ای در آنتن‌ها با کاربردهای راداری همچنین در انواع کاربردهای مخابراتی مورداستفاده قرارمی گرد در این مقاله سعی برافزایش خاصیت پره‌ای بودن آنتن شده است. آنتن طراحی‌شده دارای دو المان تشعشعی بوده و در باند فرکانسی 3.5 گیگاهرتز از ساختار دولایه تشکیل می‌شود در لایه بالایی المان‌های تشعشعی و در لایه پایینی شبکه تغذیه قرار می‌گیرد. آنتن دوالمانی ساخته‌شده دارای پهنای باند امپدانسی 8/3-4/3 گیگاهرتز, بیشینه بهره 7 dBi و عرض بیم نصف توان ˚44 و ˚104 به ترتیب در صفحه‌های H و E هست؛ که نشان از پره‌ای بودن این آنتن دارد. ابعاد کلی آنتن 105×3/32×708/3 میلی مترمربع هست. آنتن ارائه‌شده برای به‌کارگیری در دستگاه‌های راداری و دستگاه‌های G5 در باند فرکانسی 5/3 گیگاهرتز پیشنهاد می‌گردد. با توجه به تست آزمایشگاهی این آنتن می‌توان گفت که نتایج تئوری و آزمایشگاهی همخوانی مناسبی باهم دارند.
In this paper, an attempt is made to design an antenna to be used in different radar and telecommunication applications. Paying attention to antenna radiation is on the agenda And studies have been done on antenna radiation as well as their radiation pattern.Considering that the feature of the pattern with the vane feature is used in antennas with radar applications, it is also used in various telecommunication applications. In this article, an attempt has been made to increase the antenna's fan beam properties The designed antenna has two radiation elements And in the 3.5 GHz frequency band, it consists of a two-layer structure. The radiation elements are placed in the upper layer and the feeding network is located in the lower layer. The built dual antenna has an impedance bandwidth of 3.8-3.4 GHz.The maximum gain Hz is 6/76 dBi and the half power beam width is 44˚ and 104˚ in H- and E- planes.respectively which shows that this is fan beam antenna. The overall dimensions of the antenna are 105 × 32/3 ×3/708 mm square. The provided antenna is recommended for use in radar systems and 5G systems in the 3/5 GHz frequency band. According to the laboratory test of this antenna, it can be said that the theoretical and practicical results are in good agreement...
