- Next generation wireless communications terminals will demand the use of advanced component integration processes and high density packaging technologies in order to reduce size and to increase performance. This paper presents high density multilayer interconnects and integrated passives used to design high performance prototype filter for 5GHz wireless LAN receiver realized on MCM-D substrate. The thin film implementation of Multichip Module technology is identified as a useful platform for the integration of GaAs MMIC and silicon device technologies for microwave applications where performance, size and weight are critical factors. The ability of the MCM-D technology to provide controlled impedance, microstrip structures and integrated thin film passive components with useful performance in the microwave frequency regime has now been demonstrated.

- Paper substrate is one of the paramount nominees for Radio Frequency Identification (RFID) tags but at the same time it is extremely prone towards environmental changes. In this paper, antennas for UHF RFID tags on paper based substrate are investigated and analyzed for the first time to evaluate the effect of change in dielectric constant on the antenna parameters and performance. On the basis of analysis a concrete meander line antenna is proposed, designed and evaluated which has tremendous immunity towards variation in dielectric constant.

- In this paper meander line antennas with end tip loading, designed for UHF RFID tags are presented. These novel antennas are screen printed on Kapton HN for European frequency band (866-868 MHz) and for North American frequency band (902-928 MHz). Asahi ink is used for screen printing of 25 mu m thick antenna traces which remains conductive even after several times sharp bending of these tag antennas. The results show that the antennas exhibit high performance regarding smaller area, high realized gain and better return loss in the frequency band of interest. These antennas are extremely flexible which give autonomy for their applications.

- Paper substrate is one of the paramount nominees for Radio Frequency Identification (RFID) tags, for the reason that it is one of the widely and the cheapest available substrates. In this paper, for the first time quadrate bowtie antennas with round corners [1] are realized and analyzed on paper substrate for UHF RFID tags. These inkjet printed antennas exhibit high performance which give freedom for their applications. Their area is smaller than the general triangle bowtie antenna and have advantages of smaller area, better return loss in high frequency and higher gain in normal direction of antenna plane compared with general triangular bowtie antenna.d

Konferensbidrag (refereegranskat)abstract
- Radio frequency identification (RFID) antenna's versatility in terms of complete coverage of UHF RFID band (860-960 MHz), while keeping the cost factor low, is an important aspect of today's growing demand for security and tracking of multiple objects in a very short time in addition to tag's readability across the globe. This paper presents a novel inkjet printed rounded corner bowtie antenna with T-matching stubs on paper substrate which is the cheapest and widest available substrate. The antenna exhibits compact size with outstanding read range.

- This paper describes a novel Flexo, Screen and Inkjet printed rounded edges bowtie antenna with T-matching stubs on paper, Kapton (HN) and Teonex Q51 substrate. Paper is one of the paramount nominees for Radio Frequency Identification (RFID) tags, for the reason that it is one of the widely and the cheapest available substrates. Kapton (HN) and Teonex Q51 are distinguished for their flexibility and reliability. The antenna exhibits compact size with outstanding read range of 4 meters and complete coverage of UHF RFID band (860-960 MHz). The results show extreme immunity of versatile antenna against harsh environments. These antennas are flexible which give autonomy for their applications.

Process-dependence of inkjet printed folded dipole antenna for 2.45 GHZ RFID tags

Ingår i: 2009 3RD EUROPEAN CONFERENCE ON ANTENNAS AND PROPAGATION, VOLS 1-6. - NEW YORK : IEEE. - 9781424447534 ; , s. 2336-2339

Konferensbidrag (refereegranskat)abstract
- This paper focuses on the process dependence of an inkjet printed folded dipole antenna based on practical parameters in a typical inkjet printing process. We present the effect of width variations and number of overprinting times on the antenna properties such as gain, radiation efficiency and input impedance. Furthermore we investigate the read range degradation of the tag on which the antenna is attached, due to width or thickness variations. In addition, an comparison between an inkjet printed antenna on a regular paper substrate and a copper antenna on Printed Circuit Board (PCB) was made, manifesting the strong competitiveness of the printed silver antenna as a low cost solution.
