ملخص المقالة :
این مقاله به مرور برخی از آنتن های ریزنواری چاپی مورد استفاده در عینک های هوشمند می پردازد که می‌توانند فرکانس های 700-960 مگاهرتز و 7/2-7/1 گیگاهرتز و نیز وای فای نسل پنجم (85/5- 18/5 گیگاهرتز) و وای فای نسل ششم توسعه داده شده (125/7- 925/5 گیگاهرتز) را پوشش دهند تا در عینک‌های متصل بی‌سیم استفاده شوند. از آن جایی که آنتن‌های دستگاه‌های عینک هوشمند که در استاندارد ارتباطات سلولی نسل های پنجم و ششم و ارتباطات داخلی بی‌سیم وای فای نسل ششم کار می‌کنند، موضوع جدیدی است، ابتدا مطالعه کلی برای پهنای باند آنتن در محل های قرارگیری مختلف انجام می‌شود. این آنتن ها به صورت عنصرهای متقابل (تزویجی) طراحی می شوند و اکثرا بر روی زیرلایه FR4 و یا پلی کربنات قرار می گیرند. سپس به آنتن های چند ورودی-چند خروجی مورد استفاده در این عینک ها موجود در مراجع پرداخته می شود و بهره، راندمان و مطالعات آهنگ جذب ویژه به همراه حالت های مختلف انجام می شود. برای به دست آوردن انطباق خوب با موارد استفاده عملی، سر انسان همیشه در شبیه سازی ها در نظر گرفته می شود. در نهایت، مزایا و معایب آنتن های مورد استفاده در این عینک ها در مراجع مختلف با هم مقایسه می شود.
