Abstract

This work discusses the remote powering link of a passive UHF RFID tag for sensor applications. The design, implementation, and measurements of the base-station antenna, tag antenna, and the rectifier are presented. The base-station antenna is a 50 Ω rectangular patch antenna with a measured far-field gain of 3.6 dBi. The tag antenna is an inductively coupled meandered dipole antenna impedance matched to the tag chip. The measured far-field gain of the tag antenna is 1.2 dBi. The three-stage, differential-input rectifier is measured to deliver 1 mW to a 5 kΩ load with a power conversion efficiency of 65% at a distance of 1.5 meters from the base station. The rectifier is implemented in 0.18 μm UMC CMOS process.

Base station

Base station (or base radio station) is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a "land station in the land mobile service." The term is used in the context of mobile telephony, wireless computer networking and other wireless communications and in land surveying. In surveying, it is a GPS receiver at a known position, while in wireless communications it is a transceiver connecting a number of other devices to one another and/or to a wider area.

Base station subsystem

The base station subsystem (BSS) is the section of a traditional cellular telephone network which is responsible for handling traffic and signaling between a mobile phone and the network switching subsystem. The BSS carries out transcoding of speech channels, allocation of radio channels to mobile phones, paging, transmission and reception over the air interface and many other tasks related to the radio network.

Base transceiver station

A base transceiver station (BTS) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers. The network can be that of any of the wireless communication technologies like GSM, CDMA, wireless local loop, Wi-Fi, WiMAX or other wide area network (WAN) technology.
