COMm.PAT- Printed Antenna on a Non-Conventional Substrate for Communication

Abstract

Antennas used for communication purpose have been grown recently using the direct printing methods to ensure light weight technology, ease of fabrication and simply available flexible substrates in the field of printed electronics. The use of flexible non-conventional substrates in this regard has been the current issue for the provision of same results obtained as that of using a conventional substrate. In this paper, we propose low cost printed antenna on a non-conventional substrate that provides higher read range (using ISM Band) for Real time location systems (RTLS) (for e.g. wireless sensing). This antenna makes use of the deployment techniques that involve the selection of environment friendly RF substrate thatcan be served by the localized networking companies in low cost.It further evaluates the substrate characteristics and mathematical properties using the EM Simulator Software (HFSS-High Frequency Structure Simulator) followed by the fabrication of antenna, both on a conventional PCB (FR4) substrate and on a non-conventional substrate (Kodak photo paper) having different materialistic properties using a direct write printing technology. The results include the resonant frequency and the input impedance matching for the feed on a Vector Network Analyzer.
