Abstract

تتعلق الخواص الموضحة بشكل عام بتعديل نمط هوائي أصلي native antenna pattern لقمر صناعي لتهيئة اتصالات عبر القمر الصناعي. على سبيل المثال، يمكن أن يتضمن القمر الصناعي للاتصالات (120) هوائي له تجميعة مصفوفة تغذية feed array assembly (127)، عاكس reflector (122)، ومحرك خطي linear actuator (124) مقترن بين تجميعة مصفوفة التغذية (127) والعاكس (122). يمكن أن تتضمن تجميعة مصفوفة التغذية (127) مجموعة من تيارات التغذية لتوصيل الإشارات المرتبطة بخدمة الاتصالات، ويمكن تهيئة العاكس (127) لعكس الإشارات المرسلة بين تجميعة مصفوفة التغذية (127) وواحد أو أكثر من الأجهزة المستهدفة. يمكن أن يتضمن المحرك الخطي (124) طول قابل للتعديل، أو توفير موضع قابل للتعديل بين تجميعة مصفوفة التغذية (127) والعاكس (122). بتعديل موضع تجميعة مصفوفة التغذية (127) نسبة إلى العاكس (122)، يمكن أن تقوم القمر الصناعي للاتصالات (120) بتوفير خدمة الاتصالات وفقا لمجموعة من أنماط الهوائي الأصلية (210). شكل1أ
