A low-profile and meandered crossed dipole antenna design for ultrahigh-frequency (UHF) radio-frequency identification (RFID) circularly polarized (CP) tag or handheld reader application is describ...

Reducing collisions in UHF RFID systems is a crucial problem. In most anti-collision designs, the reader has to estimate the number of tags within its reading range during the interrogation process...

In this paper, the mechanical displacement and the resulting resonance shift of a basic double split ring resonator (DSRR) which is placed in different low-loss liquid-phase environments are experi...

Distance bounding (DB) protocols are crucial solutions against “distance attacks.” Traditional one-hop DB protocols can estimate an upper-bound of the physical distance between two nodes within t...

In this communication, a compact and broadband coplanar waveguide-fed meandered-slot antenna is presented. Compact size of 0.3 × 0.2 λ 2 (30 × 20 mm 2 on a 1.6 mm thick FR4 dielectric substrate) i...

In this communication, a broadband circularly polarized slot antenna with an inverted-F-shaped microstrip feed line and two linked rectangular slots in the ground plane is proposed. This antenna of...

This paper presents a compact and power efficient third-order continuous-time (CT) delta-sigma (ΔΣ) analog-to-digital converter (ADC) with a single operational transconductance amplifier (OTA). A...

Device mismatch is a key concern for high-resolution data converters. This paper presents a comprehensive study of the error-feedback (EF)-based mismatch error shaping (MES) technique. EF MES overc...

This paper deals with the synthesis and design of reader antenna for radio-frequency identification (RFID)-based dedicated short-range communication (DSRC) systems. A method for synthesizing a plan...

The dynamic process of a meta-atom (the classic double split-ring resonator) immersed in a low-loss liquid medium and illuminated by electromagnetic waves with different intensities is investigated...
