Broadband implanted UHF RFID antenna
2010 IEEE Antennas and Propagation Society International Symposium, 2010One of the priorities for sustaining high standards of medium to long term health care is to provide an effective monitoring system thus reducing the need for multiple consultations and hospital visits. In this connection, implanted biosensors, equipped with a transceiver with an antenna to establish the wireless link either to an external wearable ...

2012 20th Telecommunications Forum (TELFOR), 2012
Radio Frequency Identification (RFID) systems have been extensively used in many important applications in recent years. The band allocated to RFID technology in the UHF band differs from continent to continent but there are two main, 800MHz used in Europe and the some Asian countries while in the USA, Japan and Australia they use 900 MHz frequency ...

2010 International Workshop on Antenna Technology (iWAT), 2010
Near-field radio frequency identification (RFID) technology has been traditionally used at low frequency (LF) and high frequency (HF) bands; now developing this technology at ultra high frequency (UHF) band is of increasingly interest. Designing a UHF near-field RFID reader antenna is one of the most challenging tasks.

This chapter addresses the various design issues, requirements, and specifications in designing reader antennas for UHF RFID applications. In a typical UHF system, the RFID reader antennas are geography specific; that is, there are different antennas for different geography, namely North America, Europe, et cetera.

A Miniaturized Reconfigurable UHF Antenna
2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018This paper presents a novel planar reconfigurable meandered loop antenna that is suitable for Internet of Things (IoT) applications. This antenna reconfigures its frequency of operation between two ISM bands, 760 MHz and 575 MHz. The antenna structure also has three folded edges, six layers and with total dimensions of 40×40mm2. The top layer (layer 1)

2005 Asia-Pacific Microwave Conference Proceedings, 2006
To meet the requirements of miniaturization, high gain and wideband for UHF SAR, this paper analyses gain loss produced by reducing back cavity of short back-fire antenna. Based on pottel's formula, gain loss for the cover of reflecting disc is computed.

UHF satcom antenna architectures
MILCOM 2000 Proceedings. 21st Century Military Communications. Architectures and Technologies for Information Superiority (Cat. No.00CH37155), 2002Future UHF satellite development will require design and requirements attention to space segment antennas. Multiple beam UHF antennas are addressed for geosynchronous orbits. These antennas are significantly impacted by the large UHF percentage bandwidth and by their large size.

Manufacturing technologies for UHF RFID epidermal antennas
2016 46th European Microwave Conference (EuMC), 2016Skin-mounted electronics is the next wave beyond wearable devices for unobtrusively picking up vital signs (temperature, hydration, biopotentials…) over the body surface. The recent evolution of UHF RFID technology towards epidermal sensing applications plays a key role to provide stick on sensors with wireless powering and remote reading.

Small‐meandered coplanar antenna in UHF bands
Microwave and Optical Technology Letters, 2010AbstractA low profile, electrically small coplanar antenna with omnidirectionnal radiation is presented. The antenna is less than λ0/400 in height and λ0/14 in lateral dimension. It is matched to 50 Ω without the need for external matching. The antenna's geometry and concept design using short‐circuiting and line‐meandering techniques are presented in ...
