planar antenna for ultra high frequency uhf rfid handheld reader RFID ANTENNAS FOR READER DEVICES. RFID readers operating in UHF range are transceivers which can transmit as well as receive at one frequency. For covering longer distance the read range can be maximized with the use of directional antennas with high gain. Readers can be either fixed or portable systems. The CharlieCard is a contactless smart card used for fare payment for transportation in the Boston area. It is the primary payment method for the Massachusetts Bay Transportation Authority (MBTA) and several regional public transport systems in the U.S. state of Massachusetts. It is used on the MBTA's subway and bus services, but is not currently accepted on the MBTA Commuter Rail

A compact broadband circularly-polarised (CP) antenna is designed with a novel method for universal ultra-high-frequency (UHF) radio-frequency identification (RFID) readers. It is composed of a compact ring-shaped patch which aims to decrease the size of the antenna. A broadband magnetic coupling antenna with low far-field gain for ultrahigh frequency (UHF) radio frequency identification (RFID) near-field applications is presented in this paper. This study introduces a simple, compact broadband dual-band circularly polarised slot antenna suitable for the use in the compact universal ultra-high frequency (UHF) radio-frequency identification (RFID) reader devices and Global Positioning System (GPS) applications. In the design of ultra-high-frequency (UHF) radio frequency identification (RFID) near-field antennas, realising an antenna with electrically large size, wide frequency band, and far read range has always been a challenge. To solve these problems, a planar hexagonal broadband near-field antenna for UHF RFID applications is proposed and .
This paper proposes a nature-inspired spider web-shaped ultra-high frequency (UHF) radio frequency identification (RFID) reader antenna and battery-free sensor-based system for healthcare.
Planar Antennas for UHF RFID Reader Applications
Abstract—An Ultra High Frequency (UHF) half-loop antenna used in Radio Frequency Identification (RFID) systems is proposed with a planar patterned metamaterial structure of compact size. The size of the planar patterned metamaterial structure is (0.20λ*0.20λ*0.0023λ) mm3. This antenna consists of two metamaterial unit cells having negative . A novel design of a small planar microstrip antenna with circular polarisation (CP) that is suitable for 2.45-GHz radio frequency identification (RFID) applications was successfully designed and experimental validated. In this article, an aperture-coupled dual-band stacked antenna is proposed for handheld RFID readers. The antenna consists of two hexagonal rings, a slotted stacked patch, an E-shaped slotted ground plane, and a compact feeding network. A novel shared antenna structure is presented in this communication for near-field communication and ultrahigh-frequency (UHF)-radio frequency identification (RFID) reader applications.
