چکیده | ||
در این مقاله یک حسگر فعال مایکروویوی بی سیم با ضریب کیفیت بالا برای اندازه گیری فشار در محیط های سخت ارائه شده است. فرکانس کاری این حسگر 1.2GHz بوده و ساختار آن از دو بخش قرائتگر و تشدیدکننده SRR تشکیل شده است. در طراحی انجام شده روی تشدیدکننده یک پد متحرک قرار داده شده است که با جابه جایی آن تحت اعمال فشار، فرکانس تشدید SRR تغییر خواهد یافت. این فرکانس، با استفاده از پارامتر پراکندگی تلفات تعبیه از طریق بخش قرائتگر اندازه گیری می گردد. به منظور بهبود قدرت تفکیک، ضریب کیفیت حسگر با استفاده از یک مدار فعال با فیدبک مثبت در بخش قرائتگر افزایش داده شده است. بدین ترتیب ضریب کیفیت حسگر غیرفعال از 91/73 به 3268 در حسگر فعال بهبود یافته است. میزان حساسیت حسگر نیز در هر دو مدل غیرفعال و فعال، 70MHz/mm می باشد. حسگر پیشنهادی با استفاده از نرم افزارهای CST و ADS مورد شبیه سازی و بررسی قرار گرفته است. | ||

چکیده [English] | ||
In this paper, an active contacless microwave pressure sensor with high-quality factor for harsh environment applications are presented. The proposed sensor operates at 1.2GHz and consists of two parts of a reader antenna and a passive Split Ring Resonator (SRR). A movable pad is located above the resonator by considering an air gap between them and this gap is decreased when external pressure is applied. By decreasing the gap, the resonant frequency of SRR is decreased. The resonant frequency of SRR is measured by using the insertion loss scattering parameter through the reader part, wirelessly. To improve the resolution, the sensor’s quality factor is enhanced by using an active circuit with a positive feedback design in the reader part. Therefore, the quality factor of the passive sensor is increased from 73.91 to 3268 by using the active sensor. The sensitivity of the sensor is 70MHz/mm in both passive and active sensors. The proposed sensor is simulated and studied using CST and ADS software. | ||
