| dc.description.abstract | Meander-line and multi-layer antennas have been used extensively to design
compact UHF radio frequency identification (RFID) tags; however the overall size
reduction of meander-line antennas is limited by the amount of parasitic inductance
that can be introduced by each meander-line segment, and multi-layer antennas can
be too costly. In this study, a new compact antenna topology for passive UHF RFID
tags based on zeroth order resonant (ZOR) design techniques is presented. The
antenna consists of lossy coplanar conductors and either inter-connected inter-digital
capacitor (IDC) or shunt inductor unit-cells with a ZOR frequency near the operating
frequency of the antenna. Setting the ZOR frequency near the operating frequency is
a key component in the design process because the unit-cells chosen for the design are
inductive at the operating frequency. This makes the unit-cells very useful for antenna
miniaturization. These new designs in this work have several benefits: the coplanar
layout can be printed on a single layer, matching inductive loops that reduce antenna
efficiency are not required and ZOR analysis can be used for the design. Finally, for
validation, prototype antennas are designed, fabricated and tested. | en_US |
