In this paper, two inkjet-printed broadband antennas on flexible and organic substrates namely paper and Liquid Crystal Polymer (LCP) for the UHF Radio Frequency Identification (RFID) and sensing applications is presented. Paper is an excellent candidate for ultra low cost, flexible substrate while LCP, an organic and flex substrate shows superior electrical and mechanical characteristics while being at low cost as well. Two simple versions of CPW-fed Monopole configurations are selected: a planar configuration on LCP as well as one utilizing through vias on paper in order to prove the proof of concept of 3D functionality on paper. The antennas are fabricated using inkjet-printing technology utilizing a simple, fast, and environmentally friendly process. The design characteristics of the antennas are explained and the simulated results are compared with measurements showing good agreement.
