Abstract
A novel compact circular polarization (CP) microstrip antenna is proposed for UHF ultrahigh frequency (UHF) radio frequency identification (RFID) reader applications. The proposed antenna is composed of a corner truncated square-ring radiating patch on a substrate and a vertical slotted ground surrounding four sides of the antenna. A new feeding scheme is designed from flexible impedance matching techniques. The impedance bandwidths for S11<-10 dB and 3 dB axial ratio (AR) bandwidth are 12.1% (794.5–896.5 MHz) and 2.5% (833.5–854.5 MHz), respectively.
يُقترح هوائي ميكروستريب مدمج ومبتكر ذو استقطاب دائري (CP) لتطبيقات أجهزة قراءة تحديد الهوية بموجات الراديو (RFID) في نطاق التردد فوق العالي (UHF). يتكون الهوائي المُقترح من رقعة إشعاعية على شكل حلقة مربعة مشطوفة الزوايا موضوعة على ركيزة، ومستوى أرضي رأسي ذي شقوق يحيط بالجوانب الأربعة للهوائي. كما صُممت آلية تغذية جديدة بالاعتماد على تقنيات مرنة لمواءمة المعاوقة. ويبلغ عرض نطاق المعاوقة عند S11 < -10 dB وعرض نطاق النسبة المحورية (AR) عند 3 dB ما نسبته 12.1% (794.5–896.5 ميجاهرتز) و2.5% (833.5–854.5 ميجاهرتز)، على التوالي.
