Liquid Crystal Polymer (LCP): The ultimate solution for low-cost RF flexible electronics and antennas

Abstract

In this paper, solutions for developing low cost electronics for antenna transceivers that take advantage of the stable electrical properties of the organic substrate Liquid Crystal Polymer (LCP) has been presented. Three important ingredients in RF wireless transceivers namely embedded passives, a dual band filter and a RFid antenna have been designed and fabricated on LCP. Test results of all 3 of the structures show good agreement between the simulated and measured results over their respective bandwidths, demonstrating stable performance of the LCP substrate.

THz antennas design, developments, challenges, and applications: A review

“…57 LCP is a promising thermoplastic organic material having a low dielectric constant, a low-loss tangent (0.002-0.0025), and low thermal expansion characteristics. [58][59][60][61] The surface of PET is smooth and shiny, and it has excellent physical and mechanical properties in a wide temperature range. It has excellent electrical insulation.…”
