چکیده
این مقاله به بررسی آنتن‌های شفاف به عنوان راه حلی برای حل مشکلاتی مانند زیبایی، آیرودینامیک بودن آنتن در کاربردهای مختلف و نقش آن در کاربردهای فضایی می‌پردازد. در این مقاله، دو دستة کلی آنتن‌های شفاف بررسی شده است. در دستة اول، ساختار آنتن که در آنتن‌های متداول معمولاً از فلزات ساخته می‌شود، با استفاده از تکنولوژی فیلم نازک و یا با مشبک نمودن قسمت‌های فلزی آنتن محقق می‌شود. دستة دوم، آنتن‌های تشدیدکنندة دی‌الکتریک (DRA) شفاف است. آنتن‌های DRA متداول از جنس ماده‌ای غیررسانا ساخته می‌شود. بنابراین، با جایگزین کردن دی‌الکتریک‌های متداول با دی‌الکتریک‌های شفاف، مانند شیشه، می‌توان آنتن‌های DRA شفاف را محقق نمود. در انتها، به تبیین این نکته پرداخته خواهد شد که آنتن‌های شفاف می‌توانند در کاربردهای فضایی با ادغام با سایر ادوات، مانند سلول‌های خورشیدی به کاهش حجم و وزن ماهواره‌ها کمک کنند.
