“…However, available conductor loss [31]- [34] and radiation loss [33]- [35] formulas are dated from the 1970s or before and were not meant for describing microstrip characteristics in the tens or hundreds of gigahertz. To the authors' knowledge, no analytical formulas are available, which are optimized for describing conductor and radiation losses in a microstrip line from 30 to 110 GHz.…”

Abstract-Liquid crystal polymer (LCP) is a material that has gained attention as a potential high-performance microwave substrate and packaging material. This investigation uses several methods to determine the electrical properties of LCP for millimeter-wave frequencies. Microstrip ring resonators and cavity resonators are measured in order to characterize the dielectric constant ( ) and loss tangent (tan ) of LCP above 30 GHz. The measured dielectric constant is shown to be steady near 3.16, and the loss tangent stays below 0.0049. In addition, various transmission lines are fabricated on different LCP substrate thicknesses and the loss characteristics are given in decibels per centimeter from 2 to 110 GHz. Peak transmission-line losses at 110 GHz vary between 0.88-2.55 dB/cm, depending on the line type and geometry. These results show, for the first time, that LCP has excellent dielectric properties for applications extending through millimeter-wave frequencies.

“…Two of the three radiation loss formulas tested [34], [35], including the one used in [7], give radiation loss curves with unreasonable increases at frequencies past 30 GHz. In fact, the theoretical radiation losses from these equations give values higher than the total measured loss past approximately 80 GHz.…”

“…The ring attenuation due to radiation were computed using [12]- [14], and were found to be negligible, and therefore ignored in the computation of the attenuation due to the dielectric. The attenuation in the rings due to conductor losses were computed using formulas given in [10] and [15]- [17].…”

Abstract-In this paper, inkjet-printed UHF and microwave circuits fabricated on paper substrates are investigated for the first time as an approach that aims for a system-level solution for fast and ultra-low-cost mass production. First, the RF characteristics of the paper substrate are studied by using the microstrip ring resonator in order to characterize the relative permittivity ( ) and loss tangent (tan ) of the substrate at the UHF band for the first time reported. A UHF RFID tag module is then developed with the inkjet-printing technology, proving this approach could function as an enabling technology for much simpler and faster fabrication on/in paper. Simulation and well-agreed measurement results, which show very good agreement, verify a good performance of the tag module. In addition, the possibility of multilayer RF structures on a paper substrate is explored, and a multilayer patch resonator bandpass filter demonstrates the feasibility of ultra-low-cost 3-D paper-on-paper RF/wireless structures.
