This letter presents a dual circularly polarized microstrip antenna with wideband isolation for
radio frequency identification (RFID) reader application. The proposed antenna consists of a …

This paper presents a new reconfigurable carrier leakage canceler for UHF RFID readers,
using a directional coupler and an impedance tuning circuit to improve the sensitivity of the …

In this paper, a novel carrier leakage suppression (CLS) front-end for UHF RF identification
(RFID) reader is presented. We demonstrated through experiment in the laboratory …

In this paper the implementation of an automatic leakage cancellation for UHF (Ultra High
Frequency) RFID (Radio Frequency Identification) readers is presented. The system …

This paper presents a baseband noise reduction method in the receiver for UHF RFID
readers. The signal captured from the transmitter after passing through the main delay …

A wideband adaptive isolator for a UHF RFID reader with a minimum component count is
introduced. The operation of the device is based on a reflection from a variable load, which …

A miniaturized wideband duplex antenna is presented in this paper. The presented duplex
antenna is developed based on a dipole antenna. By changing the structure of the dipole …

A novel carrier cancelation circuit is presented for ultra high frequency (UHF) near field radio
frequency identification applications. A directional coupler, logarithmic detector and …

This article introduces a training technique suitable for an active analog carrier leakage
canceller, based on base‐band signal processing. The proposed training approach leads to …

In this paper, the design of a long read range UHF RFID reader using a novel carrier
leakage suppression method is presented. We developed and demonstrated through …
