| چکیده | ||
| در این مقاله میخواهیم یک آنتن پهن باند با قطبش دایروی طراحی نماییم. اگر امپدانس بار بهینه تقویتکننده در فرکانسهای مختلف، به هم نزدیک باشند، میتوان آنتن را بهعنوان بار بهینه برای تقویتکننده بهکار گرفت. در حالی که در این مقاله خروجی آنتن پس از اعمال سیگنال در باند فرکانسی S بررسی شده است و اثرات تابش آنتن بر روی بخش مدارات تطبیق تقویتکننده تا حدودی در نظر گرفته شده است. | ||

| چکیده [English] | ||
| Circular polarization is one of the most popular polarization approaches used in different communication systems such as radar, satellite, GPS and WiMAX systems. In this article, we want to design a wideband cylindrical antenna with circular polarization and maximum frequency coverage from 1.7 to 2.7 GHZ. If the optimum load impedance of the amplifier at different frequencies are close, the antenna can be used as an optimal load for the amplifier. In this paper the output of the antenna after application of signals in the S band is also investigated and the effects of the antenna radiation on the amplifier circuits have been considered to some extent. | ||
