This paper presents the new approach to design planar circularly polarized (CP) antennas for RFID read/write (R/W) applications in UHF band. The objective of this work has been to design an RFID R/W antenna having simple unobstructed layout and single feeding port yet demonstrating good CP performance. Two RHCP antennas utilizing the principle of EM coupling from dipole element to the parasitic structure...
The design of compact diversity antenna for wireless handset applications has been presented. The results obtained demonstrate high potential of such a design for the handset antenna systems realizing various diversity techniques, such as switched diversity, maximal ratio combining and selection diversity. This antenna structure can also be utilized in a MIMO system, where the low mutual coupling...
In this paper, we present custom design of UHF RFID tag antennas for the identification of stacked in a package CDs. The main challenge of such a design has been the size minimization of the antenna elements since the tag is allowed to occupy a circular area of 33.5 mm in diameter on the central part of an actual CD free from metallization. At the same time, tag antennas have been optimized for the...
This paper presents the design principle of a novel circularly polarized printed antenna having simple unobstructed layout and single feeding port. At the same time, the proposed antenna demonstrates good circular polarization performance. The design and optimization of two antenna prototypes have been carried out for RFID applications in 953 MHz frequency band. Both simulation and measurement data...
This paper presents the design of novel conformal fractal loop antennas proposed for the rapidly developing RF identification (RFID) wireless technology. Two antennas, based on Koch and Hilbert fractal geometries, are designed and optimized for 0.953 GHz RFID band. Key design requirement has been maximizing the antenna gain and directivity that results in increasing the read range of RFID system....
