UHF RFID Reader Antenna
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. The discussion on the design challenges and performance expectations lead to a n...
متن کاملDesign of Different Slotted Microstrip Patch Antenna for Rfid Applications
A compact cross, circular and square shaped slotted microstrip patch antennas are designed for circularly polarized (CP) radiation. Asymmetric, cross-shaped slot is embedded along one of the diagonal axes of the square patch for CP radiation and antenna size reduction. The designed antenna is contrived by using RT-Durid 5880 substrate . The design simulation and optimization is done by ADS soft...
متن کاملUltra Wideband Microstrip Diamond Slotted Patch Antenna with Enhanced Bandwidth
An Ultra Wideband (UWB) microstrip diamond slotted patch antenna with enhanced bandwidth is presented in this paper. The proposed antenna is simulated in CST Microwave Studio and fabricated for measurements. Its simulated result displays impedance bandwidth from 3.28 GHz to 19.64 GHz, whereas the measured result displays the frequency region from 2.01 GHz to 18.67 GHz. The antenna complies with...
متن کاملWideband Adaptive Isolator for UHF RFID Reader
This paper introduces a wideband adaptive isolator for UHF RFID reader with a minimum component count. The operation of the device is based on a reflection from a variable load, which is connected to a port of a hybrid coupler. The other ports are connected to the RX, TX and Antenna ports of the reader. The isolator provides an isolation of 50 dB from TX to RX at 800 MHz 1 GHz band, covering al...
متن کاملDesign of Wideband CPW Fed Slotted Microstrip Patch Antenna
Microstrip Patch antennas are very prevalent these days due to various attractive features possessed by them. Coplanar Waveguide (CPW) fed patch antenna has benefits of compact size, ease of fabrication and integration with other monolithic circuits. Moreover, the proposed design is very simple design fed with CPW feed. The proposed antenna performs dual band (1. 5 GHz and 7 GHz) operation with...
